Built as the U.S. trench-gun variant of the Stevens 520-30, this shotgun dates to the WWII period (1942–1943) and features the model’s recognizable double-hump receiver profile and right-side external slide link. It is a takedown pump-action design, retaining the original trench-gun configuration elements and layout.
Authentic U.S. martial markings are present: the left side of the receiver is marked U.S., and both the barrel and receiver carry Ordnance flaming-bomb proofs. Additional government acceptance and inspection stamps include a P proof and S inspector mark, supporting its WWII service pattern.
