This is an exceptional World War I era Winchester Model 1897 trench shotgun that falls into the known serial number range of approximately 620000-730000. Enlisted American soldiers skilled at trap shooting were issued these shotguns with 00 Buckshot ammunition and typically positioned to be able to fire at enemy hand grenades in midair. Early Model 1897 shotguns have the ability to rapid slam fire using the slide action forend with the trigger held down, which also made them highly effective for close combat and earned them the troop nickname "trench sweeper". A slam-fired 1897 could be carried with mobility and cover a large area with flying lead, a valuable asset in a war where most machine guns were too heavy and awkward for a single operator to swing around unsupported in a close quarters fight. The Model 1897 in American hands was so effective and brutal in trench warfare that the German government protested to outlaw use of it in combat. Features a six-hole handguard/bayonet adapter with the original patent date marking at the left muzzle end. The left side of the barrel is stamped with the two line address followed by "12 GA." and "CYL", with the top of the barrel and receiver both stamped with a circled Winchester "WP" proof at the breech. The slide bar has the model and trademark information. Grooved forearm and smooth pistol grip stock with a checkered hard rubber buttplate. Length of pull is 13 7/8 inches. Includes bayonet and scabbard.
