OPINION

The appellant (Fedrick) appeals from a summary judgment in favor of the appellee (Borg) entered by the District Court on the several grounds that the provision of the Statute of Frauds, California Commercial Code (C.C.C.) § 2201(1) and (2), barred Fed-rick’s action against Borg for the breach of an alleged oral bid or contract to supply and sell certain motor driven pumping units (pumps), and relief could not be granted under any theory of equitable estoppel. We affirm.

Fedrick raises two issues on review. Did the District Court err in determining that:

Fedrick originally instituted the proceedings in the Superior Court of California for the County of Marin. Borg timely removed the action to the District Court pursuant to 28 U.S.C. § 1446 and moved for summary judgment. Jurisdiction in the District Court and in this court is established.

The undisputed facts pertinent to review are:

Fedrick had prepared a bid as the prime contractor on a construction project under the auspices of the United States Bureau of Reclamation (Bureau). At 9:50 a. m. on May 30, 1974, approximately ten minutes before the time fixed for the submission of bids on the project and after Fedrick had fixed the amount of its intended bid, Borg was asked and did submit a telephonic offer to supply and sell Fedrick the pumps required by the specifications of the prime contract for the price of $826,550, with an increased cost escalation. Borg’s telephonic figure was $450,000, plus, lower than the next lowest bid which Fedrick had received for the pumps. Whereupon Fedrick reduced its intended prime contract bid figure of $15,766,693 by an even $200,000.

On the following day, Fedrick in turn orally indicated to Borg that in the likely event it was awarded the prime contract, Fedrick intended to purchase the pumps from Borg.

Some three weeks later, on June 20, representatives of Fedrick and Borg met to discuss the contemplated transaction. During the meeting, Borg expressed concern that its proposed exceptions might not be acceptable to the Bureau. To avoid potential problems, Borg, as an alternative proposal, suggested certain modifications to bring the pumps more in accordance with the Bureau’s published specifications. Thereafter on the same day Borg wrote Fedrick detailing the proposed modifications and fixing a revised price of $1,114,-572 for the pumps.

Fedrick’s counsel responded by letter dated June 25 denying that Borg’s original telephonic offer was subject to the additional exceptions as claimed by Borg and further stating in its pertinent parts:

Borg replied by letter dated July 15 that it was prepared to abide by the original telephonic offer as Borg claimed it was made or the June 20th modified offer.

The prime contract was awarded to Fed-rick on July 11 next, and on July 19 Fed-rick’s counsel wrote Borg a letter stating in its pertinent parts:

Thereafter Fedrick purchased the pumps from another supplier for the price of $1,162,200, incurring thereby the alleged damage of $95,903 sued for in the proceedings.

Issue 1:

We are, as was the District Court, bound to look to the substantive law of California for the resolution of the issues. Erie Railway Co. v. Tompkins, 304 U.S. 64 , 58 S.Ct. 817 , 82 L.Ed. 1188 (1938).

We believe that throughout their dealings concerning the pumps, Fedrick and Borg were “merchants” within the meaning of that term as used in C.C.C. § 2201(2). See C.C.C. § 2104; 1 Anderson, Uniform Commercial Code, 283, § 2-201:50, and 219-22, §§ 2-104:4-2-104:7 (2d Ed. 1970). So it follows from the undisputed facts that Borg’s telephonic bid of May 30 in and of itself was subject to revocation by Borg during and awaiting “a reasonable time [for Fedrick's] writing in confirmation of the contract and sufficient against [Fedrick was] received and [Borg after receipt has] reason to know its contents.....” C.C.C. § 2201(2).

The dispute over the actual terms and exceptions in Borg’s telephonic bid raised by Borg at the June 20th conference, and especially Borg’s letter of June 20 proposing modifications of the telephonic bid, constituted a clear and decisive communicated revocation of the telephonic bid prior to any “writing” from Fedrick as permitted under C.C.C. § ,2201(2). However, in order to deal with Fedrick’s letters to Borg of June 25 and July 19, we will assume arguendo that Borg’s telephonic bid or offer in and of itself remained outstanding.

We are satisfied that at most Fedrick’s letters were self-serving statements of actions taken by Fedrick in reliance upon Borg’s telephonic bid.

We then deem Fedrick’s “writing” of June 25, as well as the subsequent letter of July 19, each to be far short of constituting a “confirmation of the contract.” The express language of the second paragraph of the quotation from Fedrick’s letter of June 25 speaks of a future intended executed agreement incorporating “the price and terms of the bid you submitted.” Again, Fedrick’s letter of July 19 speaks of future action and acknowledges that Borg would not accept a purchase order with the specifications required by Fedrick. None of Fedrick’s writings were sufficient to bind *856 Fedrick to the terms of Borg’s telephonic bid. 1 Anderson, supra, 283, § 2-201:51, n. 8. See Doral Hosiery Corp. v. Sav-A-Stop, Inc., 377 F.Supp. 387, 389 (E.D.Pa.1974).

Accordingly we conclude that by virtue of C.C.C. § 2201(1), Borg’s telephonic bid of May 30 in and of itself is not enforceable by Fedrick as a contract for the sale and delivery of the pumps.

The District Court did not commit error on this issue.

Issue 2:

Fedrick would avoid the barring effect of C.C.C. § 2201 through the application of the doctrine of estoppel. Fedrick claims that its cause of action is not actually for a breach of contract but rather in substance a cause for Borg’s unlawful revocation of its telephonic bid or offer after reliance thereon by Fedrick to its detriment.

Fedrick first relies upon the rationale of Drennan v. Star Paving Co., 51 Cal.2d 409, 414-15 , 333 P.2d 757 (1958); H. W. Stanfield Constr. Corp. v. Robert McMullan & Son, Inc., 14 Cal.App.3d 848, 852 , 92 Cal.Rptr. 669 (1971); and Saliba-Kringlen Corp. v. Allen Engineering Co., 15 Cal.App.3d 95, 111 , 92 Cal.Rptr. 799 (1971). The District Court with reference to those authorities succinctly stated the rationale of those authorities as being “clear ... in the context of competitive bidding, an offer once relied upon is irrevocable even though it lacks consideration.” However, the District Court quickly pointed out that Drennan and its progeny involved contractors bidding for construction work and materials subcontracts as opposed to vendors of specific goods such as Borg. Consequently C.C.C. § 2201 was not applicable nor considered in those authorities.

We find those California authorities lacking of definitive adjudication of this issue. Also our independent search for controlling California authority is wanting. Accordingly we are, as was the District Court, directed under Erie to reach the resolution of this issue as the Supreme Court of California would probably reach under the same facts. Furthermore, for us the “[ajnalysis by a district judge of the law of the state in which he sits ... is entitled to great weight . . . That determination ‘will be accepted on review unless shown to be clearly wrong.’ ” United States v. Pollard, 524 F.2d 808 (9th Cir. 1975); Owens v. White, 380 F.2d 310, 315 (9th Cir. 1967); Minnesota Mutual Life Insurance Co. v. Lawson, 377 F.2d 525 (9th Cir. 1967); and Bellon v. Heinzig, 347 F.2d 4 (9th Cir. 1965).

The District Court laid considerable stress upon the Arizona authority in Tiffany Inc. v. W. M. K. Transit Mix, Inc., 16 Ariz.App. 415 , 493 P.2d 1220, 1225-26 (1972), and stated:

We conclude that the Supreme Court of California in considering this issue would probably adopt the rationale, or a variation thereof, in Tiffany rather than render C.C.C. § 2201(1) and (2) a nullity by extending to vendor’s oral bids for sale and delivery of specific goods the doctrine of estoppel as applied in Drennan and its progeny to subcontractors’ work and materials oral bids.

Next Fedrick relies upon the rationale of estoppel as enunciated in Monarco v. Lo Greco, 35 Cal.2d 621, 623-24 , 220 P.2d 737 (1950). In Monarco , a decedent failed to devise real property honoring his oral promise which had been relied upon to the prejudice of the promisee. The Supreme Court of California applied the following sound equitable doctrine of estoppel:

The following authorities, Irving Tier Co. v. Griffin, 244 Cal.App.2d 852, 863 , 53 Cal.Rptr. 469 (1966); Sloan v. Hiatt, 245 Cal.App.2d 926 , 54 Cal.Rptr. 351 (1966); Mintz v. Rowitz, 13 Cal.App.3d 216, 224-25 , 91 Cal.Rptr. 435 (1970); and others have interpreted Monarco as requiring a showing of either unconscionable injury or unjust enrichment to preclude the Statute of Frauds defense.

Rather than indulging in a detailed analysis and discussion as to why those authorities are distinguishable, we reach directly for the Achilles heel of Fedrick’s equitable stance. Fedrick candidly concedes that Borg was not unjustly enriched in the situation, but does strenuously contend it has suffered an “unconscionable injury” at Borg’s hands.

The “unconscionable injury” claimed by Fedrick is the amount of $95,903 incurred when Fedrick was forced under its prime contract to purchase the required pumps from another supplier at a higher price following Borg’s revocation of its telephonic bid. The precise issue and contention of a resulting unconscionable injury from such a predicament was met and decided adversely to Fedrick by this court in Caplan v. Roberts, 506 F.2d 1039 (9th Cir. 1974).

In Gapian, a supplier of heavy construction equipment was sued for breach of an oral sales contract when it refused to deliver the goods to plaintiff and instead conveyed to plaintiff’s customers. This court, based upon California authorities, affirmed the District Court’s summary judgment for the defendant with this statement:

Caplan controls here, and we are satisfied that the only injury Fedrick might have suffered from Borg’s refusal to supply the pumps under the telephonic bid amount was “the loss of the profit [Fedrick] was to make on . . . ” its prime contract with the Bureau.

We conclude that Borg was not estopped from relying upon C.C.C. § 2201(1) in the course of action taken, and the District Court did not err on this issue.

The summary judgment in favor of Borg entered by the District Court on January 24, 1975 is affirmed.

AFFIRMED.
