This is an excellent example of a late WWII, all blued Winchester Model 12 Trench Gun that was manufactured circa 1944-45. The Winchester Model 12 and Model 97 Trench Guns were the primary U.S. combat shotguns in WWII and Korea and even into Vietnam by both the Marine Corp and US Army, with most being rebuilt and reparkerized over time. Consequently original unaltered WWII examples are extremely rare today, The barrel is 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 breech end of the barrel is stamped with a small Ordnance Dept. "Shell and Flame" insignia with the circled "WP" Winchester proof on the barrel and receiver. The right front end of the receiver is also roll stamped with the Ordnance "Shell and Flame insignia/U.S.". The serial number, "1013426" is roll stamped on the barrel extension and receiver. This shotgun is fitted with a walnut stock and pump handle with the left side of the stock stamped with the boxed "G.H.D." inspection proof over the 1/4 inch cross-cannon U.S. Ordnance inspection proof. The walnut stock and forearm have a varnish finish with the black checkered hard rubber buttplate with the circular Winchester logo. The shotgun is fitted with the WWII pattern four hole all blued heat shield/bayonet lug. The stock has a sling swivel and the larger bail wire sling swivel located on the bayonet lug. Includes a WWI model 1917 Remington bayonet and green leather scabbard. The bayonet has the "Eagle Head/Ordnance Bomb proof/U.S." on the right side with the obverse having "1917/Remington" and the scabbard is the correct WWI pattern with the metal tip and throat. It is complete with a Boyt/42 marked leather sling.

Excellent with 90% plus of the blue finish overall with some minor thinning on the sides of the receiver and top rear end of the barrel, where it get picked up at. The stock and pump handle are both in very fine condition with a clear sharp proofs with 97% of the varnish remaining with numerous scattered minor handling marks/light pressure bruises on the sides. The bayonet and scabbard are both in very fine condition and the sling is excellent. Mechanically excellent. A top condition early all blued Winchester Model 12 trench shotgun.
