This M1 Carbine has been fitted with an original M1A1 Paratrooper stock. Barrel is marked "UNDERWOOD/8-43/flaming bomb", the front receiver ring has standard markings and the heel is marked "UNDERWOOD/2358628/T". The "T" indicates the receiver was manufactured by Intertype Corp. for Underwood. "R" marked blade front and "I.R.C.O." marked stamped adjustable rear peep sights, "AI" marked type 3 barrel band/bayonet lug, flat top bolt, toggle safety, and "M" marked magazine catch. Low wood stock with a four-rivet handguard. The grip is stamped with a single "P" proof on the front face, "crossed cannons" stamp on the right side and "RI/3" on the bottom. 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 and the drawing number cast on the inside surface. With a M4 bayonet with M8 sheath, "U.S." marked 1943 dated G.B. Mfg Co. double magazine pouch with two standard magazines, "U.S." marked 1952 dated S. Froehlich Co. M2 double magazine pouch with two extended M2 pattern magazines, and a "U.S." marked 1944 dated Atlas Awning carbine jump sleeve.

Very fine as arsenal refurbished and converted to M1A1 configuration. 95% of the post-war parkerized finish remains with some light edge wear, and cycling marks, scattered small dings, and surface scratches. The stock and handguard set are also fine with scattered small dings, light scratches, and some wear on the metal components. Mechanically excellent. The accessories are very fine overall.
