The Winchester Model 12 and Model 97 trench shotguns were the primary U.S. combat shotguns used in World War II and Korea and even into Vietnam by both the U.S. Marine Corps and Army. Original, unaltered World War II examples are considered rare today given almost all were rebuilt over time. This example was manufactured in 1943. The barrel is roll stamped with the two line Winchester address/patent dates followed by "-WINCHESTER-/-TRADE MARK-" and "MODEL 12-12 GA.-2 3/4 CHAM./CYL." The top breech end of the barrel has a small flaming bomb insignia and the bottom is "43" dated. Both the barrel and front edge of the receiver are stamped with the circled Winchester "WP" factory proof mark. The right of the receiver is also roll stamped with "U.S." and the flaming bomb insignia. Correctly fitted with the World War II pattern four-hole heat shield with "W" marked bayonet lug, pistol grip walnut stock and serrated pump handle, and the left of the stock is stamped with the boxed Ordnance "G.H.D." inspection mark above a small 1/4 inch crossed cannons cartouche, with a checkered hard rubber buttplate with the circular Winchester logo. The stock has a sling swivel and the larger bail wire sling swivel located on the bayonet lug. The matching serial number is roll stamped on the underside of the barrel extension and receiver. Includes a green canvas web sling, and a March 3, 1961 dated letter indicating this shotgun was sold from dealer A.G. Hanak to a family member of the current consignor. Provenance: A.G. Hanak; Property of a Gentleman
