Okla. Stat. tit. 12A, § 2-506
Oklahoma Code Comment
(1) This section is more extensive than previous Oklahoma law. A bank who paid a draft accompanied by a negotiable bill of lading acquired title to the bill. State Nat. Bank of Oklahoma City v. Wood, 43 Okl. 251, 142 P. 1002 (1914); Marsh Milling & Grain Co. v. Guaranty State Bank, 69 Okl. 222, 171 P. 1122, L.R.A. 1918D, 704 (1918); City National Bank of Hobart v. State, 73 Okl. 316, 176 P. 232 (1918). There were no suggestions, however, that the bank acquired any greater rights than as a purchaser of the draft or bill of lading.
(2) Previously in Oklahoma, a bank which, on its own initiative, purchased a draft and bill of lading, which it in turn sold to the buyer, was treated as any other vendor, and was held to warrant the genuineness of the bill. American Nat. Bank- of, Lawton v. J. Rosenbaum Grain Co., 148 Okl. 232, 299 P. 447 (1931). This section of the Commercial Code, however, is not dealing with that type of situation. It governs only those transactions in which the bank has honored or purchased the draft at the request of the buyer. In that event, the financing agency does not warrant the genuineness of the bill, and is entitled to reimbursement from the buyer even though the bill is a forgery. However, since Section 2 - 103(1) (b) requires commercial good faith in all transactions, the bank must exercise reasonable care to detect any apparent defects on the face of the document.
