Stevens 520-30 U.S. Marked 12 Gauge (S13415)

WWII U.S. military trench gun with 20" barrel. The shotgun is in the proper serial number range and is also marked U.S. on the left side of the receiver. The bore is excellent. The action works perfectly. The stock and forend are very good. The buttstock has a factory slotted sling swivel. Has original butt plate. The barrel is a non-marked Stevens replacement barrel. Overall excellent.
