This is a spectacular example of a rare, World War II, all parkerized Winchester Model 12 trench gun. 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 extremely rare today given almost all were rebuilt and reparkerized over time. 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 Ordnance Dept. "Shell and Flame" insignia and the bottom is "43" dated. Both the barrel and front edge of the receiver are stamped with the circled Winchester "WP" factory proofmark. The right of the receiver is also roll stamped with "U.S." and the Ordnance "Shell and Flame insignia" This shotgun is fitted with a pistol grip walnut stock and 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 U.S. Ordnance crossed cannons escutcheon. The matching serial number is roll stamped on the underside of the barrel extension and receiver. The ribbed forearm and buttstock has a dry oil type finish and a black checkered hard rubber buttplate with the circular Winchester logo. Correctly fitted with the World War II pattern four hole heat shield with "W" marked bayonet lug. The stock has a sling swivel and the larger bail wire sling swivel located on the bayonet lug. Includes a correct 1917 dated M1917 bayonet, 1918 dated olive drab green leather scabbard, tan canvas sling, 1943 dated U.S. canvas ammunition pouch, and a sealed twenty-five round box of World War II Winchester 00 buckshot 12 gauge ammunition.

Excellent, retains 98% plus original parkerized finish with a few light handling marks, some light cycling wear, and crisp markings and edges in the metal overall. Wood is also excellent with defined edges and rich oil finish, some light handling marks, and crisp stampings. Mechanically excellent. Included bayonet is very fine. This is one of the finest examples of a Winchester Model 12 we have ever had the opportunity to offer at Rock Island Auction!
