Excellent World War II U.S. Winchester Model 12 Slide Action Trench Shotgun Offered here is a spectacular example of a highly desirable 1943 production factory parkerized Winchester Model 12 trench gun. Original high condition examples of these are rare today given their very high usage rate. Approximately 6,800 Model 12 trench shotguns were produced by Winchester during World War II for the war effort per page 6 of "U.S. Winchester Trench and Riot Guns" by Joe Poyer. The trench shotgun saw effective use in the hands of the U.S. military in the trenches of World War I, for clearing Japanese bunkers and fortifications in the Pacific Theater of World War II, in the Korean War, in the jungles of the Vietnam War, the Gulf War, and even into the Global War on Terror in the 21st century. They are simply one of the most effective combat tools in American service and are a must have for U.S. military collectors today. Of the small handful of the different primary issue trench shotguns of World War II, the Winchester Model 12 is one of the most desirable today. The Winchester Model 12 and Model 97 trench shotguns were the primary U.S. combat shotguns used in World War II and Korea and into Vietnam by both the U.S. Marine Corps and Army. 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, and the bottom is "43" dated. Both the barrel and front edge of the receiver are stamped with the oval bordered Winchester "WP" factory proof mark. The right of the receiver is also roll stamped with "U.S." and the flaming bomb. The matching serial number is roll stamped on the underside of the barrel extension and receiver. It has a four-hole heat shield with bayonet lug assembly marked "W" on the left side, a serrated walnut pump handle, pistol grip walnut stock, and a black checkered hard rubber buttplate with the circular Winchester logo. The stock has a sling swivel and a larger bail wire sling swivel is located on the bayonet lug. 14 inch length of pull.
