John Olin went to Ithaca for the 3 1/2" 10 gauge not his own company.
The Western Cartridge Co.'s 3 1/2 inch Magnum-Ten gauge shell and the Magnum-framed Ithaca NID to handle it were well under development before the Olins bought the defunct Winchester Repeating Arms Co.
The deal for Western Cartridge Co. to buy Winchester Repeating Arms Co. was made on December 22, 1931, but wasn't really concluded until the Haskins & Sells auditor's report dated 20 February 1932.
The Western Super-X 10-gauge 3 1/2 inch Magnum shell first appears in the
Western Ammunition for Rifle, Revolver and Shotgun booklet dated April 1, 1932, and the Magnum-Ten NID first appears in the second printing of Ithaca Gun Co.'s 1932 catalogue --
wherein they misstate that the Chas. Askins Magnum-Ten is a No. 5E when in fact it was really a No. 4E.
