Most areas of worn finish show discoloration from oxidation. There are scattered nicks, scuffs and scratches. There are tool marks around some screw and pin heads.

The heat shield is secured to the bayonet lug assembly with six rivets, two on each side and two on the top, all polished flush.

Our Assessment: After observing the Great War for the first three years, it became clear to the U.S. that serious close-range firepower was needed in trench warfare. The Model 1897 Trench grade was an evolution of this idea. The pre-existing Winchester Model 1897 was modified by adding a perforated steel heat shield over the barrel which protected the hand of the user from the barrel when it became over-heated, and an adapter with bayonet lug for affixing an M1917 bayonet. They were so effective and brutal in combat that the German high command once announced they would execute any US soldier captured with one in his possession. The 1897 Trench Gun saw continued use in the second World War and after, a testament to the quality of the gun. This example appears to be an inter-war commercial production gun and, curiously, has British proof marks. Based on the production date, lack of a hole in the barrel for a bead sight, the post on the magazine cap for the bayonet lug and the factory “CYL” marking, not to mention the lack of any martial markings, it appears that there was someone in England so impressed by the trench guns’ performance that they had to have their own. It certainly would have been a comforting arm to have around if the Germans had ever invaded the home islands. This shotgun is in Very Good condition with some repaired damage to the stock, wear in the metal consistent with its age and intended use, a quite good bore and strong mechanics. Trench guns are nearly all collectible, and the commercial trench guns were even less common. A commercial trench gun with British proof marks has got to be one of the least common you’re going to find, so we’re sure this will take a prized place in a collection.
