Manufactured in late 1943 with an original WWII paratrooper folding stock. This is a late war model that was refurbished for the Korean War. The rear of the receiver is marked "UNDERWOOD/4057437". The barrel is marked "UNDERWOOD/9-43/ordnance bomb" and it is fitted with all original GI parts including an M3U conical flash hider. It is fitted with a milled adjustable rear sight marked "HI", with a type 3 barrel band/bayonet lug marked "KI", flat Inland bolt with a type three Inland marked trigger housing and operating slide. It is fitted with an original WWII low wood M1A1 folding paratrooper stock. The handguard is an early two rivet version with the deep sighting groove. The stock is stamped with a partial crossed cannon cartouche on the right side. The wire stock has a leather cheek pad held on with steel rivets, with an oiler bottle held in place by a steel loop. Butt is cast metal with wide checkering. Magazine is absent.

Very fine as arsenal refurbished with 95% parkerized finish. Displays some scattered handling marks. Stock is very good, with some deep indentations and scratches. Mechanically excellent.
