MURRAH, Chief Judge. These consolidated appeals are from separate judgments in private Section 4 antitrust suits against defendant-appellants. 38 Stat. 731, 15 U.S.C.A. § 15. Each of the suits is based upon the same alleged 20-year combination and conspiracy under Sections 1 and 2 of the Sherman Antitrust Act, 15 U.S.C.A. §§ 1, 2, to monopolize, attempt to monopolize and restrain interstate trade in the source, production and processing of vanadium-bearing ore on the Colorado Plateau, and the interstate marketing of its metallurgical products. Each of the plaintiffs claims damages for injury to his business and property by reason of the predatory effects of the alleged master conspiracy. The suits largely involve common issues of facts and law, and were consolidated for trial. The complaint in the so-called Balsley case (No. 6321) states the basic combination, conspiracy and operative facts common to all of the cases. It is east in two counts. Count one is by thirty-six named independent ore miners on the Colorado Plateau' who mined and sold vanadium-bearing ore to defendants during all or a part of the alleged combination and conspiracy, and who complain of injury by reason of alleged monopolistic and conspiratorial price-fixing practices of the defendants. The second count of this complaint is a class action under 23(a) (3) F.R.Civ.P., 28 U.S.C., in which the plaintiff-miners in count one seek to enforce the several rights of the same class of unnamed independent miners on the Colorado Plateau. On the latter count, the factual question of the existence of the conspiracy and its total impact on the class was submitted to the jury, leaving to the court the function of assessing the amount of damages to any member of the class after notice and hearing. The defendants have perfected an interlocutory appeal under Section 1292, 28 U.S.C., 72 Stat. 348, from an order on a jury verdict in favor of the class, in which they challenge the propriety of the class action, and that matter will be hereinafter fully considered. In Number 6319, Nisley and Wilson are independent millmen on the Plateau, who claim to have been injured in their business and property by reason of the impact of the combination and conspiracy. Wade and his co-plaintiffs in Number 6320 were millmen, who also operated mining claims on the Plateau. They claim to have been injuriously excluded from competition with the defendants by force of the alleged monopoly and- conspiracy. To each of the separate claims, appellants have pleaded the 4-year statute of limitations as a bar to recovery. § 4B Act of July 7, 1955, 69 Stat. 283; 15 U.S.C.A. § 15b. The applicability of the statute of limitations involves a complexity of statutory suspension, tolling and tacking, relied upon by plaintiffs to avoid the statutory bar and to sustain recovery for all matters complained of from 1938 to the filing of the suits in 1958. Since the incidence of the statute of limitation goes to the heart of the right of recovery, we shall first consider the measure of its applicability. The combination and conspiracy is alleged to have been formed in 1933, and recovery thereon was allowed from 1938 to the date of the filing of the suits. When the suits were filed, Section 4 of the Clayton Act had been amended in 1955 (69 Stat. 283, § 4B, 15 U.S.C.A. § 15b), to provide a uniform 4-year statute of limitations to actions arising thereunder, and providing also that no cause of action barred under existing law on the effective date of the Act (January 7, 1956) shall be revived. And, Section 5 of the Clayton Act, as amended in 1955, provided in presently material part that: “(b) Whenever any civil or criminal proceeding is instituted by the United States to prevent, restrain, or punish violations of any of the antitrust laws, but not including an action under section 15a of this title the running of the statute of limitations in respect of every private right of action arising under said laws and based in whole or in part on any matter complained of in said proceeding shall be suspended during the pendency thereof and for one year thereafter; Provided, however, that whenever the running of the statute of limitations in respect of a cause of action arising under Section 15 of this title is suspended hereunder, any action to enforce such cause of action shall be forever barred unless commenced either within the period of suspension or within four years after the cause of action accrued.” From this it follows that the right to recover damages accruing by reason of the alleged conspiracy prior to June 1954 is barred, unless the running of the statute is suspended by the pendency of a criminal information against these defendants filed in September 1948, and terminated on June 2, 1957. These suits were filed within one year after termination of the information, and the appellees rely upon its pendency and a prior indictment against the same defendants filed in June 1946, and dismissed on the date of the filing of the criminal information in September 1948. To further toll the statute beyond the pendency of the indictment and subsequent information, appellees invoke the so-called 1942 war-time tolling statutes, 56 Stat. 781, as amended, 59 Stat. 306, 15 U.S.C.A. § 16 note under which all statutes of limitation applicable to antitrust violations were suspended until June 30, 1946. If, as the trial court held, these asserted private rights of action can be said to be “based in whole or in part on any matter complained of” in the criminal information together with the indictment, and the war-time tolling statutes are applicable, they cumulatively operate to toll or suspend the running of the 4-year statute to October 10, 1942, and thus allow recovery for the actionable period laid in the suits, i. e., 1938 to 1958. But, appellants earnestly contend that their plea in bar should have been sustained because these suits are not based in whole or in part upon the information or the indictment, and in any event, the indictment cannot be tacked to the information so as to suspend the bar beyond the pendency of the information. In the first place, they say that under prevailing law, in order for the private suits to be based in whole or in part on the information, the matter complained of therein must be “virtually identical” to the matter complained of in the information, i. e., the private litigants must rely not only upon the same general conspiracy, but upon the same means to achieve the same objectives of the same conspiracy. In sum, the appellants take the position that the words “private right of action” in Section 5(b) mean an overt act committed in furtherance of a general conspiracy; and the words “based in whole or in part on any matter complained of” mean in whole or in part of any such overt act complained of in a government proceedings; and that the criminal information is therefore ineffectual to suspend the running of the statute of limitations against any overt act or right of action asserted in the private suits which are not identifiable in the information. Making application of this admittedly strict construction of the statute, and considering each overt act as a “private right of action,” they point out that the asserted rights of action and the information do not coincide either with respect to time or subject matter. It is apparently true, as appellants suggest, that alleged overt acts in furtherance of the conspiracy prior to December 13, 1941, were not chargeable in the indictment or information. And, it is true of course that overt acts occurring after June 1, 1946, were not within the indictment filed on that date, or within the information, which did not charge any subsequent overt acts. Nor did the information complain of the activities of the defendants while acting as agent of the government under a contract with a government agency known as the Minerals Reserve Company; nor of a conspiracy to monopolize or restrain trade in the uranium content of the ore, as did the private suits. Neither did it complain of the monopolization or conspiracy to monopolize vanadium ore claims nor of individual monopolization or individual attempts to monopolize. Antitrust actions of this kind are, to be sure, concerned with overt acts done in furtherance of the injury complained of, and there is good authority for construing the statutory words “based in whole or in part on any matter complained of” tó mean overt acts complained of by the United States in a government suit. See Steiner v. 20th Century-Fox Film Corp., 9 Cir., 232 F.2d 190. This interpretation of the critical words is said to be supported by Congressional history of the legislation, and by the preceding and related Subsection (a) of Section 5, which provides in substance that a final judgment or decree rendered in a criminal prosecution under the antitrust laws to the effect that a defendant had violated such laws, shall be prima facie evidence against such defendant in any suit or proceedings brought by any party against such defendant under such laws as to all matters respecting which the judgment or decree would be an estoppel as between the parties thereto. Construing the two paragraphs together (5(a) and 5(b) ), and making application of the general rules of estoppel, it is suggested that since a final judgment in a government suit would be admissible as evidence in a private suit only as to matters complained of and decided in the government suit, the running of the statute of limitations with respect to matters not complained of would not be suspended. See Steiner v. 20th Century-Fox Film Corp., supra. The two paragraphs are indeed complementary and should be construed together. See Sun Theatre Corp. v. RKO Radio Pictures, 7 Cir., 213 F.2d 284; Fifth & Walnut, Inc. v. Loew’s, Inc., 2 Cir., 176 F.2d 587, 593. But, we do not think they are necessarily co-extensive in their frame of reference. The purpose of the first paragraph of Section 5 was “to minimize the burdens of litigation for injured private suitors by making available to them all matters previously established by the Government in antitrust actions”; and to that end “to confer, subject only to a defendant’s enjoyment of its day in court against a new party, as large an advantage as the estoppel doctrine would afford had the Government brought suit.” Emich Motors Corp. v. General Motors, 340 U.S. 558, 71 S.Ct. 408, 95 L.Ed. 534. The corollary purpose of the tolling provisions of the second paragraph of Section 5 is to vouchsafe the intended benefits of related government proceedings by suspending the running of the statute of limitations until the termination of the government proceedings, and allowing the private suitor one year thereafter in which to prepare and file his suit. The competency of a government judgment in a private suit is necessarily restricted to the requirements of due process. But the tolling of the statute during the pendency of the government litigation is not so limited. Making application of the estoppel doctrine in a private antitrust suit, which alleged that the monopolistic acts and practices of defendants in a local area were steps in the perpetration of a broad nation-wide conspiracy between and among the defendants, we sustained the trial court’s admission of the final judgment in the nation-wide conspiracy case as prima facie evidence of the existence of such conspiracy and its localized impact upon the business of the private plaintiff. Loew’s, Inc. v. Cinema Amusements, 10 Cir., 210 F.2d 86. See also Twentieth Century-Fox Film Corp. v. Brookside Theatre Corp., 8 Cir., 194 F.2d 846. Sun Theatre Corp. v. RKO Radio Pictures, supra, seems contra, i. e., see 213 F.2d at page 290. But even so, we do not think the tolling provisions of the second paragraph of Section 5 are confined to or governed by the evidentiary rules of estoppel, necessarily prevalent in the first paragraph. If we accept the appellants’ interpretation of Section 5(b), a Section 4 plaintiff would be put to the necessity of bringing suit on the same conspiracy alleged in the government suit, or suffer the bar of the statute as to every overt act not complained of in the government suit. This interpretation would lead to a multiplicity of suits with duplication of proof. It would add to the burdens of the private suitor to the harassment of the defendants. We do not think Congress intended any such result. Rather, we think Section 5(b), as amended, was intended to suspend the running of the statute on a Section 4 claim during the pendency of a government-instituted suit which complained of all, or a part of the means relied upon by the private plaintiff to effectuate the same general combination and conspiracy. These private suits alleged substantially the same conspiracy against the same defendants as in the government suit. They relied upon the same documentary and oral proof to establish the conspiracy, and they also relied “in part” on the same means for the effectuation of the same conspiracy. There was substantial identity of subject matter, and this was sufficient to suspend the running of the statute. The criminal information was filed on the date the indictment was voluntarily dismissed. The information alleged substantially the same combination and conspiracy against the same parties and substantially the same means for its effectuation. From the time of the filing of the indictment on June 1, 1946, until the termination of the suit on the information, there was pending a government-instituted antitrust suit on which these private suits were based in part, and they operated to suspend the running of the statute of limitations as to such suits. The appellants claim that the war-time tolling statutes, supra, were' superseded by the enactment of the 4-year federal statute of limitations, and were therefore inoperative to toll the running of the statute beyond the filing of the criminal indictment in June 1946. They point to the expressed Congressional concern over the prolongation of antitrust litigation by virtue of the wartime tolling statute, and the disparity brought about by the application of state statutes of limitation. And, they assert the Congressional purpose of the 1955 Amendment was to supersede both the war-time statute and the state statutes. In order to curtail undue prolongation of litigation, the 4-year statute expressly provided that no action barred under existing law on the effective date of the 1955 Amendment would be revived thereby. But we can discern no Congressional purpose to bar any right of action which subsisted by virtue of existing law on the effective date of the Amendment.- Indeed, one of the declared purposes of 5(b) (see Footnote 1) was to “extend the tolling period not only for the duration of the Government’s antitrust suit, but for 1 year thereafter.” Under the proviso in 5(b), supra, a suit to enforce a cause of action under Section 4 is not barred if commenced “either within the period of suspension [i. e., during the pendency of the government suit and one year thereafter] or within 4 years after the cause of action accrued.” These suits having been commenced within the period of suspension, i. e., one year from the date of the termination of the information, the 4-year statute was inoperative during that period. See Goodfriend v. Kansas City Star Co., D.C., 158 F.Supp. 531; April v. National Cranberry Ass’n, D.C., 168 F.Supp. 919. In that respect, our eases are factually different from Herman Schwabe, Inc. v. United Shoe Machinery, 2 Cir., 274 F.2d 608; United Shoe Machinery v. International Shoe Machinery Corp., 1 Cir., 275 F.2d 459, where the private suits were commenced more than one year after the termination of the government suits, and the 4-year statute became applicable to the asserted causes of action. The United States Vanadium Corporation and Electro Metallurgical Company, wholly owned subsidiaries of Union Carbide, were dismissed from the pending criminal information on May 21, 1956. The appellants contend that the information thereupon ceased pending against these two defendants, and inasmuch as no private suit was filed against them within one year from the date of termination, the 4-year statute is applicable to all matters complained of against them; that such statutes of limitation are available to the parent corporation; and that having raised the statute as a defense, the trial court erroneously refused to apply it. In other words, Carbide contends that it may be held liable without regard to the statute of limitations running against its subsidiary “only if it actively participated in the conspiracy." In United States v. United States Vanadium Corporation, 10 Cir., 230 F.2d 646, we held that the criminal proceedings against these particular defendants abated upon their dissolution and merger with the parent corporation. Melrose Distillers v. United States, 359 U.S. 271, 79 S.Ct. 763, 3 L.Ed.2d 800, seems to be to the contrary. But, we have no need to decide whether under that ease the running of the statute was suspended during the pendency of the information against the parent defendant, for the actions surely terminated when they were dismissed on May 21, 1956. From that date there was no pending government suit against these defendants to suspend the running of the statute as against them. And, since these suits were not commenced within one year after the termination of the government suits, the 4-year statute applies, unless, as the appellees concede, Union Carbide actively participated in the conspiracy. Without detailing the pertinent evidence at this stage of the appeal, suffice it to say that there was evidence tending to show that these two wholly owned subsidiaries, together with other subsidiaries, were actually incorporated departments or divisions of the parent corporation, by which it carried on an integrated business of mining, processing, converting- and marketing vanadium-bearing ore and its refined products. It was not the-purpose of the statute of limitations to require the plaintiffs to institute suit against these dissolved corporations in order to avoid the running of the statute as to acts committed in their name while under the direction and control of the parent corporation. Appellants take the further position that in any event, the asserted claims were barred by applicable state statutes of limitation. The theory seems to be that the state statutes of limitation which were applicable and suspended on the effective date of the Amendment in January 1956, thereupon commenced to run on that date, and operated to bar the actions when these suits were commenced in June 1958. The simple and conclusive answer is that even before the 1955 Amendment and the advent of the uniform 4-year statute, the second paragraph of Section 5 of the Clayton Act (38 Stat. 731) operated to suspend the running of all statutes of limitation in respect to each and every right of action Which was based in whole or in part on any matter complained of in a government suit. And since, as we hold, the pending information and indictment operated to suspend the running of the statute on these asserted causes of action until one year after termination of the information, they were not barred when the 1955 Amendment became effective. And, since these suits were com.menced within the 1-year period, they are not barred by any statute of limita“tion, state or federal. We agree with the trial court that the 4-year federal statute of limitation is applicable; that it was suspended from June 4, 1958 back to June 1, 1946 by the pendency of the government suits; tolled from June 30, 1946 back to October 10, 1942 by the war-time tolling statute; and therefore all causes of action accruing before October 10, 1938 are barred. This brings us to the merits of the cases. Since the Balsley action presents the central issues on appeal, we will first consider the points raised in that case. SOME BASIC AND COMMON PACTS. Carnotite and rosceolite ore, found in paying quantities on.the Colorado Plateau, contain both vanadium and uranium. When vanadium is processed and reduced into ferrovanadium, it is useful in the manufacture of alloy steel, and is sold primarily to steel companies in competition with other ferroalloys. Vanadium-bearing ore is first milled and processed into vanadium oxide (V2O5)— usually at mills or plants located in the mining vicinity — and in this form has no commercial utility. It is then shipped to reduction plants in the Eastern part of the United States where it is converted into ferrovanadium and sold in that form to the steel industry. In the forepart of this alleged conspiracy, and prior to the advent of atomic energy, uranium was used primarily in the ceramic industry, and only high grade uranium ore was marketable for that purpose. The prime element of carnotite and rosceolite ore was vanadium, and in the milling process to produce vanadium oxide, the uranium was discharged as tailings or refuse. The Vanadium Corporation of America (VCA) was the pioneer and principal producer of ferrovanadium until the Union Carbide and Carbon Corporation (UCCC) entered the industry in 1926. Prom about 1911 until about 1932, VCA obtained most of its raw material from a high grade vanadium mine in the Republic of Peru. In the beginning, the ore bodies yielded about 50 percent V2O5 and the ore was shipped directly to VCA reduction plants in the State of Pennsylvania, where it was smelted and refined directly into ferrovanadium. As mining progressed down through the ore bodies, however, the vanadium content diminished until by 1930, the ore yielded less than 10 percent V2O5, and it became necessary to fuse the ore before reducing it to ferrovanadium. This intermediate process took place originally in Peru at the mine site on an experimental basis and at the reduction plant in Pennsylvania. Because of the diminishment of vanadium content in the ore, and depressive market conditions, VCA ceased to operate its Peru mine in 1931, and for a year or two thereafter supplied its market demand from inventory of fused oxide and ferrovanadium. About this time, VCA acquired vanadium ore deposits and an oxide mill on the Colorado Plateau at Naturita, Colorado, but apparently did not mine the ore or operate the mill until 1940. Meanwhile, and in 1926, UCCC, after a survey of the available supply of vanadium-bearing ore on the Colorado Plateau and the potential market for ferrovanadium in the steel industry, purchased extensive ore deposits and a vanadium oxide mill at Rifle, Colorado. The Rifle mines and mill were acquired in the name of the wholly owned United States Vanadium Corporation (USV). It also acquired a ferrovanadium plant in Ohio, which it later transferred to its wholly owned Electro Metallurgical Company (Electromet). And still later, it acquired other similar plants in the Eastern part of the United States. It marketed the ferrovanadium to the steel industry through the Electro Metallurgical Sales Corporation (Electromet Sales), another wholly owned corporation. In 1932, the USV.Colorado mines and mill were closed due to an oversupply (between 3,000,000 and 4,000,000 pounds) of vanadium oxide which was stored at the Colorado plant. In 1933, Electromet sold to VCA 1,000,000 pounds of vanadium oxide (V2O5) for 800 a pound, to be delivered in monthly quantities before December 1934. From 1932 through 1939, VCA purchased from Electromet a total of 2,-825,583 pounds of vanadium oxide, which was approximately 20 percent of its then current requirements. In 1936, USV constructed a vanadium oxide mill at Uravan, Colorado, 13 miles from VCA’s dormant plant at Naturita. And, in 1938, the capacity of the Uravan plant was doubled, with structural steel furnished by VCA. With an upsurge in market demand due to national defense and export requirements in 1937, VCA increased its imports from Peru, and in mid-1940, activated its mine and oxide plant at Naturita. In 1942, VCA constructed a vanadium oxide plant for the United States government at Monticello, Utah, and operated it under an agreement with the Metals Reserve Corporation, a United States government agency, until February 1944; and again from February 1945 until April 1946. Also in 1942, USV rebuilt and reactivated its Rifle plant and constructed another plant for the United States government at Durango, Colorado, which it operated until June 1948, at which time the plant was leased by VCA. From 1939 to 1942, USV mined and processed ore from deposits belonging to and controlled by VCA and delivered the vanadium oxide to VCA under a toll agreement for 650 and 750 per pound. Approximately 90 percent of the ore milled by USV at its plants came from its own mines. About 70 percent of the ore milled by VCA at its plants came from its own mines. The remainder of the ore was purchased from independent miners on the Colorado Plateau, such as the plaintiffs in the Balsely group. From the very outset, and until 1942, the operating mills on the Colorado Plateau paid identical prices, i. e., 210 a pound, for 2 percent vanadium ore. In 1942, the price was simultaneously increased by both companies to 310, and this basic uniform price prevailed on the Colorado Plateau until the filing of this suit in 1958. From 1933 to at least 1948, most of the vanadium-bearing ore mined on the Colorado Plateau was milled in plants which were either owned or operated by one of the two companies. The product of these plants, that is V205, was sold on identical price schedules, except sales or interchanges between the two companies. During all of the period complained of (1938 to 1958), VCA and UCCC, through its subsidiaries, controlled almost 100 percent of the ferrovanadium market, with approximately 66 percent to VCA and the remainder to Electromet. These sales were made to the steel industry on identical price schedules under yearly “requirement contracts.” ' In sum, it may be taken as an established salient fact that from 1938 until •1948, most all of the domestic vanadium-bearing ore was produced on the Colorado Plateau; that approximately 80 percent of such ore was mined from properties owned by the two companies; and that most of the ore was milled in vanadium plants owned or operated by one of the two companies. Almost all of the vanadium oxide was converted to ferrovanadium in plants owned by the two companies. The two companies controlled the market for ferrovanadium which was sold to the steel companies on requirement contracts at identical prices. From this it is fair to say that the appellants possessed monopolistic and price-fixing powers to bring about the combination and conspiracy complained of in the complaint. Our first question is whether they used those powers for the predatory and unlawful purposes complained of. . EVIDENCE OF COMBINATION AND CONSPIRACY. There was competent evidence in support of the alleged combination and conspiracy to the effect that. UCCC .entered the vanadium field in 1927 for the avowedi purpose of exploiting ferrovanadium as a steel alloy. Its integrated corporate structure was designed to mine, mill, produce and sell vanadium to the steel- industry at prices which would enlarge the market in competition with other alloys; and, that by pursuing this aggressive policy in a depressed market, it built up a large inventory of vanadium oxide at its Rifle plant. And, it being no longer profitable for VCA to import Peru ore for its depleted markets, there could be nothing sinister about its purchase of 1,000,000 pounds of USV’s surplus oxide to supply its market for ferrovanadium. At 800 a pound, over a cost of about 400 or 500, the transaction was profitable and advantageous to USV — indeed, mutually advantageous. From the evidence in the record, it is fairly inferable, however, that contemporaneously with the USV-VCA sale in 1933, USV was faced with the alternative whether it would lower the price of oxide and ferrovanadium and attempt to garner a greater share of the alloy market, and perhaps eliminate VCA as a competitor, or negotiate and cooperate with VCA as a friendly competitor. And, it is fairly inferable that it finally resolved to pursue the latter course. There was evidence of friendly negotiations between the two companies concerning centralized mining and milling of the oxide on the Colorado Plateau. The negotiations went so far as to contemplate the reconstruction of VCA’s Naturita dormant mill, to be operated by USV; and that it was finally decided to construct the mill at Uravan, 13 miles away. The construction of the mill in 1936/ and its enlargement in 1938, followed by the agreement between the two companies, whereby USV would mine and mill VCA's ore, to be converted into ferrovanadium in VCA’s plants to supply VCA markets, is evidence of collusive cooperation between the two companies. There was direct evidence to the effect that beginning in 1936, USV kept a very close surveillance on the activities of competitors and potential competitors on the Plateau. And, when in 1938, independent miners and millers began to spring up-with the increase in market demand for ferrovanadium, USV immediately took steps to forestall competition. USV commenced purchasing ore from the independent miners in 1938, and in 1939 published its first ore price schedules, in which it quoted a base price of 210 per pound for 2 percent ore, which was its estimated cost of producing its own ore. The evidence showed that USV inaugurated an aggressive policy of acquiring the mining claims of the independent miners who were unable to operate their properties at ore prices offered by USV, the only purchaser; that it acquired claims tributary to independent millers in order to dry up their source of supply; and that they purchased the output of independent millers while they had a surplus of oxide, in order to take it off of the market. With the continued increase in the demand for ferrovanadium, VCA decided to activate its plant at Naturita in 1939. When the plant opened in 1940, they commenced purchasing ore from independent miners, and there was evidence to the effect that VCA agreed with USV that it would pay the same price of 210 per pound for 2 percent ore. With the accelerated demand, there was some deviation from the base price in the way of bonuses and hauling differentials, but in the main, the parties pursued and policed the same price schedule. In recognition of the necessity for increased domestic production of vanadium for the war effort, the United States government entered into a contract with USV on May 9, 1942, whereby USV was designated as its agent to construct and operate the Durango plant and to purchase vanadium-bearing ore suitable for treatment in the plant “at reasonable prices not to exceed 500 per pound of vanadium pentoxide (V205) delivered at suitable loading points.” There was evidence that at about the same time, USV and VCA mutually agreed to raise the price of 2 percent vanadium ore purchased from independent miners to 310 per pound, and that they maintained this price schedue for ore purchased at both VCA’s Naturita plant and USV’s plant throughout the period complained of. From this it is fair to infer, as did the jury, that some time prior to 1938, the appellants combined and conspired to monopolize or attempt to monopolize, and to restrain interstate trade in the vanadium industry; that they took affirmative and effective steps to fix the prices for the raw ore, fused oxide and ferrovanadium, and to forestall and eliminate competition and to divide the market between them. THE MEASURE AND AMOUNT OF DAMAGES. The Balsley miners claimed and were permitted to recover damages based upon the difference between the price they were paid for the vanadium content of the ore sold to the appellants, and the prices they would have received but for the antitrust violations. They claimed damages based upon the value of the uranium content in the ore delivered to the appellants, and for which they were not paid. They presented their case by dividing their claims into four damage categories: “(1) Vanadium content of carnotite ore: This category included: “a. All purchases of vanadium by appellants as private buyers from October, 1938 to June, 1958. “b. All purchases of vanadium by U. S. V. during a period in which they were commissioned by M. R. C. to acquire carnotite ore. This period ran from May, 1942 to February, 1944. “(2) Uranium content of carnotite ore: This category included: “a. All purchases of uranium by appellants as private buyers until the Atomic Energy Commission’s ore buying program. The period ran from October, 1938 to April, 1948. “b. All purchases of uranium by U. S. V. during period commissioned by M. R. C. to acquire carnotite ore. This period ran from May, 1942 to February, 1944.” In their answer to interrogatories submitted in the form of the verdict for the unnamed plaintiffs in the class action, the jury specifically found that as to the vanadium purchases by the defendants from the unnamed-miner plaintiffs for the period October 1938 through March 1948, the price per pound for 2 percent vanadium ore should have been 40$, and 35$ for the period from April 1948 through May 1958. As to purchases of 2 percent vanadium ore by USV as agent for MRC from June 1942 to February 1944, the jury found that the price should Rave been 50$ per pound. With respect to uranium sales, the jury denied any recovery for the period January 1939 through December 1942. For the period January 1, 1943 to August 31, 1945, the jury found that the per pound price of -uranium ore should have been $1.25, and $2.50 per pound for the period September 1, 1945 to March 31, 1948. The form •of the verdict for the named plaintiffs did not specify the per pound price which the plaintiffs should have received for the periods set out and as specified in the verdict for the unnamed plaintiffs. However, the recovery as to each class, i. e., the named and unnamed, was based upon the same proof and necessarily computed .according to the same formula. The amount of damages awarded each named plaintiff was computed on the basis of ■their individual ore settlement sheets, which, in each transaction, reflected the .amount of ore delivered tp the purchaser ■(USV or VCA), its vanadium content, and the price paid therefor, as against the price the jury found they would have received but for the violations. For the purpose of calculating the amount of uranium content of the ore sold during these periods, the jury justifiably found that the approximate average ratio of vanadium to uranium for the vanadium-uranium properties on the Colorado Plateau was six to one. For the purpose of reviewing thé factum and amount of damages awarded in the judgment, we shall conveniently observe the same periods and categories as did the jury in arriving at its verdict. But, we shall first consider the recover-ability of damages for vanadium ore purchases while USV was acting as the agent for MRC (May 1942 to February 1944) in the prosecution of the government’s ore-buying policies. The earnest contention is that the appellants could not have conspired to fix prices with respect to ore purchased by USV acting as agent for the government. As we have seen, the agency agreement between USV and MRC dated May 9, 1942, did make and constitute USV the agent of the government to construct a vanadium plant at Durango, Colorado, and commissioned USV to exert its best efforts to purchase for the account of the government vanadium ores for treatment at the government plants, at reasonable prices not to exceed 50$ per pound V205. The trial court was requested to instruct the jury in substance that the government itself could not violate the antitrust laws; that an agent for the government, acting within the scope of his authority, was likewise immune, and that if the authorized activities of the agent were validly conferred, the fact that the agent may have had illegal private motives in the performance of his authorized duty was irrelevant. It is true, as appellants suggest, that the antitrust laws are inapplicable to government activities. And, it may also be taken as equally true that since the government acts only through its agents, such agents are likewise immune from liability under the statute while acting within the scope of his authority in the furtherance of a declared governmental policy or legislative scheme. Parker v. Brown, 317 U.S. 341, 63 S.Ct. 307, 87 L.Ed. 315; Ashe-ville Tobacco Board of Trade v. F. T. C., 4 Cir., 263 F.2d 502. Cf. Atchison, Topeka & S. F. Ry. Co. v. Aircoach Transportation Ass’n, 102 U.S.App.D.C. 355, 253 F.2d 877. But there is nothing in this agency contract to justify the inference that the government intended to transgress the antitrust laws. The contract does not purport to authorize USV to fix prices, restrain trade or achieve a monopoly in the vanadium industry, and we will not lightly infer an intention to do so. Cf. Maryland and Virginia Milk Producers Ass’n v. United States, 362 U.S. 458, 80 S.Ct. 847, 4 L.Ed.2d 880; United States v. Radio Corp. of America, 358 U.S. 334, 79 S.Ct. 457, 3 L.Ed.2d 354; United States v. Borden Co., 308 U.S. 188, 60 S.Ct. 182, 84 L.Ed. 181. The court, correctly we think, instructed the jury that if the defendants used the agency powers “for the purpose of carrying out or assisting any combination or conspiracy to restrain trade or to monopolize trade in the vanadium industry or any actual monopolization thereof, the fact that they might have been government agents at the time does not immunize their conduct;” and that “a violation of the antitrust laws may be carried out by acts which, standing alone, may be legal, but if they form a part of an illegal combination or conspiracy to restrain or monopolize, then you may consider them with all of the other evidence in the case to arrive at your verdict.” The court then proceeded to particularize to the effect that if, in the execution of the government ore-buying program, USV arrived at prices paid the miners as a result of agreement with VCA to pursue a plan to monopolize the vanadium industry, the fact that it was acting as agent for MRC would not immunize otherwise unlawful conduct. “And this is so” said the court, “though government officials knew and tacitly approved the ore-purchasing programs which violated the antitrust laws.” Both the Durango plant and the Monticello plant were constructed with government funds to be operated by USV and VCA respectively for the account of the government in recognition of the urgent need for additional vanadium ore concentrates. The USV-MRC agency contract was designed to subsidize the mining of marginal ores for production in the government-owned and privately operated plants. USV was authorized to and did negotiate various prices for mined ore, depending upon its percentage content which bore upon the cost of mining and transportation. The evidence shows that many contracts were negotiated with miners on the Plateau, including those in the Balsley group, for the payment of varying prices, some below the 310 scheduled price, and some above. Of course, a negotiated price based upon grade, haulage and a 10 percent profit, is inconsistent with a conspiracy-fixed price, unless it can be said that the negotiated prices were in themselves designed to further the objectives of the combination and conspiracy. The appellees contend in effect that the negotiated prices were discriminatorily directed toward the effectuation of the monopoly. It is difficult to determine from this record to what extent the negotiated prices were tainted by the subsisting conspiracy price of 310. Some basic facts are important guides in determining to what extent the found conspiracy permeated and influenced the MRC prices. First, there was positive evidence to the effect that contemporaneously with the advent of the government ore-buying program and the USV-MRC contract of May 9, 1942, USV and VCA officials agreed to raise the base price of ore from 210 to 310 for 2 percent ore, and that throughout the period of the ore-purchasing agency, this basic price prevailed for private purchases of ore for USV and VCA privately owned plants at Naturita and Uravan, despite the accelerated demand for vanadium ore. USV’s ore-purchasing officer became its principal ore-purchasing officer under the agency contract. And, it seems fair to say that he was at least in doubt concerning whether and to what extent the 310 privately established base price was to govern the government purchases. Indeed, it is difficult to discern whether he truly served the interest of the MRC ore-buying program, or whether he utilized his powers as a government agent to further the interest of the price-fixing and monopolistic design of an employer, USV. There was evidence to the effect that at least some of the plaintiff miners were unaware of USV’s discretion to pay a reasonable price for the ore not to exceed 500 per pound. One of the negotiated purchase contracts was between USV as agent for MRC and VCA, dated March 11, 1943, providing for the payment of 480 per pound, plus hauling allowance for 1.5 percent ore. While all of this ore was milled in the government-owned-VCA-operated Monticello plant, at a loss to VCA, it was the highest price paid for ore on the Plateau under the MRC ore-purchasing program. Many of the contemporaneous contracts provided for much lower prices for the same percentage ore. The so-called negotiated prices paid under the USV-MRC agency contract for ore to be processed in government-owned plants, were not intended to yield a profit to the millers. Indeed, the record shows that the Monticello and Durango mills were operated afí a loss to the government. The prices were not open-market competitive prices, and ordinarily would not be a permissible element of damages based upon what was received and what would have been received but for the conspiracy. But even so, if, as the jury apparently believed, the prices paid to the independent miners in relation to the prices paid to VCA were discriminatory and intended to effectuate the monopolistic designs, the miners are entitled to recover the difference between the negotiated discriminatory prices and the price which the jury found the miners should have received but for the conspiracy, having in mind the relevant economic factors, including the negotiated price contemporaneously paid to VCA. In the last analysis, it was for the jury to determine whether the negotiated price was actually a part and parcel of the appellants’ design to achieve a monopoly, and whether the negotiated prices to the plaintiff-miners were discriminatorily different from those paid to VCA under the same circumstances. On the whole record, we cannot say that the jury’s finding to the effect that the plaintiff miners should have been paid 500 per pound for 2 percent vanadium ore purchased by USV under its agency contract with MRC is without rational basis in fact and reason. FACTUM AND AMOUNT OF DAMAGES FOR VCA-USV PRIVATE VANADIUM ORE PURCHASES FROM OCTOBER 1938 TO MARCH 1948 Appellants complain of the allowance of damages for ore sales during 1938 and 1939, on the grounds that since VCA did not commence purchasing ore on the Plateau prior to mid-1940, there could have been no price-fixing conspiracy, hence no evidence of controlled or predatory prices. But there was evidence from which the jury could reasonably infer that the 1938 and 1939 purchases of ore were made in pursuance of a monopolistic design; and that the prices paid to the independent miners were intended to effectuate and perpetuate the monopoly. The appellants were therefore liable for the difference between a competitive price and the monopolistic one. The appellees concede the burden of proving (1) that the appellants violated the antitrust laws; (2) that the violations had an injurious impact on the plaintiffs; and (3) that there was sufficient economic data from which the jury could estimate or proximate the amount of damages. The court clearly instructed the jury to the effect that plaintiffs had the burden of establishing by the greater weight of the evidence the alleged conspiracy to fix prices of uranium-vanadium bearing ore, and to monopolize or attempt to monopolize the vanadium industry; that such unlawful acts proximately caused injury to the property and business of the plaintiffs; that if they found by a greater weight of the evidence that the defendants did so conspire to fix prices and monopolize or attempt to monopolize, and that the plaintiffs were damaged thereby, they might resolve any uncertainty as to amount against the wrongdoer and assess damages upon inferential, as well as direct and positive proof. In that respect, the jury was told that in making their estimates of damages to the plaintiffs, and particularly the price which they would have received but for the violations of the antitrust laws (determined by the jury to be 400 per pound for this period), they should consider all of the economic information produced at the trial, including the prices paid under the metal reserve program, and the price range authorized under the MRC-USV agency contract, the cost of production viewed in the light of the profits made, the prices received by VC A for ore it sold to USV as agent for MRC, and any reasonable allocation which the evidence permits of the defendants’ profits as between ore, oxide and ferrovanadium. The appellants complain of a myriad of errors in these instructions. First, they say that even conceding arguendo the existence of a conspiracy, there is no competent evidence to prove with the requisite degree of certainty that the plaintiffs suffered legal injury as a result thereof. Specifically, they deny that the uniform prices paid for the ore — 210 to May 1942 and 310 thereafter — was not the fair market price of the ore. And, in that regard, they point to the fact that no other purchaser and miller of ore on the Colorado Plateau paid more than the so-called fixed prices. They call attention to the periods of soft markets and surpluses for ferrovanadium. There is no direct evidence tending to show what vanadium ore would have sold for in a free market, absent the conspiracy. As we have seen, the MRC prices were not free market prices, and standing alone were not evidence thereof. But, it is significant, we think, that during the period of war-time scarcity, when the government, through the MRC was subsidizing the production of vanadium ore through negotiated prices not to exceed 500 per pound V2O5, and was paying VCA 480 per pound for 1.5% ore, the fixed price of private purchases remained uniform and consistent at 310 per pound. In these circumstances, we think it not improper to allow the jury to consider the MRC prices in determining whether, absent the conspiracy, the plaintiff-miners would have received more. During all the period between 1938 and 1948, the defendants were the dominant purchasers and millers of vanadium ore on the Colorado Plateau. They were practically the only processors and sellers of ferrovanadium, the finished product. The jury found from competent evidence that the defendants fixed the price of the raw material which they purchased, and the price for which the finished product would sell, and that they controlled and divided the market between them. The mere existence of an unlawful conspiracy to fix the price of vanadium ore on the Colorado Plateau, purchased by the defendants from the plaintiffs, does not in and of itself prove legal injury to the sellers of the ore, i. e„ that they would have received more for the ore, absent the conspiracy. At the same time, the prolonged existence of a price-fixing conspiracy in an integrated industry such as ours is proof of damages to those whose prices are directly affected thereby. In that respect, our case is noticeably akin to Mandeville Island Farms v. American Crystal Sugar Co., 334 U.S. 219, 68 S.Ct. 996, 92 L.Ed. 1328. And see also Fox West Coast Theatres Corp. v. Paradise Theatre Building Corp., 264 F.2d 602, where Judge Fee said for the Ninth Circuit, “The mere unlawful combination over a period of time to eliminate competition is proof of damage”; and, in Richfield Oil Corp. v. Karseal Corp., 271 F.2d 709, the Ninth Circuit again said that applied restraint would patently result in some loss of business. The appellants also attack that part of the instructions of the court which told the jury that in estimating damages, they could take into consideration the cost of production viewed in the light of the profits made as allocated between the raw ore, the oxide and the ferrovanadium. The court admitted evidence over the objection of the appellants, of their net profits from the sale of vanadium oxide and ferrovanadium. And, the jury was permitted to determine damages on the basis of the profit spread between the cost of the vanadium ore and the price of oxide and ferrovanadium. Loss of profits has been accepted as constituting an element of recoverable damages where they are capable of being measured or estimated on a reasonable basis. See Twentieth Century-Fox Film Corp. v. Brookside Theatre Corp., 8 Cir., 194 F.2d 846; Atlas Building Products Co. v. Diamond Block & Gravel Co., 10 Cir., 269 F.2d 950; Bigelow v. R. K. O. Radio Pictures, 327 U.S. 251, 66 S.Ct. 574, 90 L.Ed. 652. It would seem reasonable to say that profits from sales of a finished product in a monopolistic market are distinctly relevant to the free market value of the raw materials, the cost of which was a constituent element of such profits. This is especially so when considered in the context of an integrated industry. It seems relevant to consider that from 1934 to 1947, ferrovanadium was sold in a controlled and restricted market for $2.70, $2.80 and $2.90 per pound, depending on grade. And, there was some evidence to the effect that based upon the price paid for vanadium ore, and the cost of conversion into the finished product, the appellants could have profitably paid as much as 80^ per pound for the V2O5 contained in the ore purchased from the plaintiff-miners. This data was based upon calculations which, while attacked, cannot be said to be wholly without factual basis. In these circumstances, we cannot say that the jury’s finding to the effect that the free market price of 2 percent vanadium ore for the period October 1938 through March 1948 was 40¡S per pound instead of 310 was clearly erroneous. DAMAGES FOR THE URANIUM CONTENT OF THE ORE. As we know, appellees claimed damages for uranium sales made to the appellants from 1938 to the advent of the Atomic Energy Commission in April 1948. The jury awarded no damages for sales made prior to January 1,1943. The appellants first deny the existence of any conspiracy or monopolistic designs with respect to the purchases of uranium ore. The appellees take the position that the conspiracy alleged, and which the jury found, related to and affected the purchase of carnotite ore on the Colorado Plateau which, as we know, contained both uranium and vanadium on a ratio of about six parts vanadium to one part uranium; and that from the very beginning, appellants conspired not to pay the miners anything for the uranium content in the ore, while recognizing its value and while selling it to the government. A bit of background is important to a consideration of our question. As we have seen, at the beginning of the mining operations on the Colorado Plateau, the uranium content of the carnotite ore was considered a valueless impurity, relegated to refuse in the form of tailings. The splitting of the atom in 1939, and the publication in 1940 of literature on the potential value of uranium as a fissionable material, fired the imagination of some scientists and industrialists, including some of the officers and employees of Union Carbide. As early as 1939, USV constructed a small recovery plant in connection with its Uravan operations. High grade uranium sludge was recovered from the tailings. About the same time, Union Carbide, through one of its subsidiaries, began experimenting with uranium as a source of energy, and in 1940, USV sold and delivered 1,000 pounds of uranium sludge to another subsidiary for experimental purposes. But, these experiments did not result in the production of uranium oxide for commercial purposes, and as far as we can determine from the record, no commercial use was made of it. The so-called Manhattan District was formed in 1942 by the government for the specific purpose of secretly developing and producing the atomic bomb. In the latter part of 1942 or the first part of 1943, Manhattan entered into classified “cost-plus-a-fixed-fee” contracts with USV for the construction and operation of two “sludge plants,” one at Uravan, Colorado, and another at Durango; and a refining plant at Grand Junction. The sludge plants were designed to manufacture uranium sludge or slime (designated by a secret code) from sand tailings which had accumulated from the operation of the vanadium mills at the same sites. The Grand Junction plant was designed to refine the sludge into uranium oxide, also designated by a secret code. Contemporaneously with these construction and operation contracts, the government contracted with USV to purchase the refined oxide from USV and the sludge from VCA. About the same time, the government-owned plant at Monticello was activated for the processing of uranium sludge under a contract between Manhattan and MRC. About the same time, the government commissioned a subsidiary of Union Carbide called Union Mines, to develop processes for the benefication of uranium and to survey the resources of uranium on the Colorado Plateau, and make recommendations “for the acquisition of the strongest possible control of the products and disposal of such resources.” Also in the early part of 1943, Manhattan enlarged VCA’s Tandawanda ceramic plant, which had been used to process high grade uranium for the ceramics industry. Throughout the period of the so-called Manhattan project, this plant continued to be known as a ceramic plant for security reasons. All of these contracts contained the legally required provision against disclosure of any information relating to the contracted work under penalty of law. These contracts remained secret and classified until unclassified in 1957. None of these contracts contemplated a profit to the appellants for any of the work done or performed, or for the products processed and delivered. Most, if not all, of the high grade uranium sludge came from the workings of tailings which had accumulated from the vanadium operations, during which the uranium content in the ore was valueless. Notwithstanding all these activities, only 12% percent of the uranium utilized in the Manhattan project came from the Colorado Plateau. Throughout the period of development of the atomic bomb, and until the dropping of the first bomb in 1945, Manhattan looked primarily to high grade uranium ores from the Belgian Congo for its source of fissionable material. The production of uranium on the Colorado Plateau was considered only as a by-product of the vanadium ore operations. There was no concentrated effort toward the exploitation of the uranium content in the carnotite ore until the advent of the Atomic Energy Commission in 1947. Indeed, appellees accuse, the appellants of conceitedly subordinating the production and marketing of the uranium content in ,the Ore'to the conspiratorial agreement to ■fix the price and control ;the market of vanadium products. With the dropping of the bomb and the ending of the war in 1945, the demand for uranium as fissionable material began to phase out. Having developed the bomb which ended the war, the mission of the Manhattan District was accomplished. While the government apparently continued to honor its existing uranium contracts with appellants after 1945, there was no urgent need or market for uranium. Matters drifted along until Manhattan went out of existence at the end of 1946 and the Atomic Energy Commission took over in January 1947. There'has never been a free market for U3O8 as fissionable material. The government is and always has been the sole and only purchaser at prices fixed or negotiated with the suppliers. Viewed in this perspective, it seems doubtful whether the pre-existing vanadium monopoly was broad enough to embrace an agreement not to pay the plaintiff-miners for the uranium content of the carnotite ■ ore purchased by the appellants during the period in which the government was purchasing uranium sludge processed from accumulated tailings at the-vanadium mill sites. We will, however, resolve all doubts in favor of the findings which are implicit in the jury .verdict, and assume the existence of a conspiracy to monopolize or attempt to monopolize the market for the uranium content of the carnotite ore, which is the subject matter of this suit. But even so, we are unable to discern how the appellees can be said to have suffered any compensable harm as a result of the activities of the appellants in connection with either the MRC vanadium ore-purchasing program, or the Manhattan-uranium project. The USV-MRC contract of May 9, 1942, authorizing USV to purchase ore suitable for treatment in government-owned plants at reasonable prices not to exceed 500 per pound for vanadium oxide, did not authorize USV to pay anything for the uranium content of the ore. Indeed, there is nothing in the record to indicate that the government’s vanadium ore-buying program contemplated the payment for or the recovery of the uranium content of the ore purchased under, the USV-MRC contracts. With the advent of the uranium-purchasing program in 1943, the appellants, and for that matter everyone else, was forbidden under penalty of law to acknowledge that the uranium content in the ore was being saved or utilized. It is agreed that the Manhattan project for the acquisition of uranium ore on the Colorado Plateau was a security secret. It may well be that a portion of the vanadium content of the miners’ ore found its way into the sludge which the appellants sold to Manhattan under the contracts, but even so, the contracts did not contemplate a profit to the appellants, and the record shows that operating profit, if any, was negligible. In these circumstances, we can find no factual basis for the award of damages based upon ore purchases prior to the dropping of the atomic bomb in July 1945. But appellees assert that there was no reason for secrecy after July 1945, and therefore no valid grounds for not compensating the appellees for the uranium content of ore purchases after that date. Subsequent to the dropping of the bomb, and in 1946 and 1947, the government entered into contracts with the appellants for the purchase of U3Os in the form of sludge and sodium uranate, highly refined uranium products. While these contracts were coded and classified, they explicitly provided for the payment of the U3O8 contained in the ore, “whether such ore is produced or mined by the contractor or purchased from an outside source.” These contracts, as revised and amended, are irrefutable evidence of the amount of uranium contracted to be sold to the government during the years 1945, 1946 and 1947, and the unit price to be paid therefor. In January 1946, USV issued a price schedule providing for the payment for uranium at 300 for .75 percent uranium ore. VCA issued its first price schedule in the spring of 1947 for 500 per pound for similar ore. Giving full effect to the combination and conspiracy as it embraced the uranium content of the ore purchases, we are brought
