Fine example of a scarce Irwin-Pedersen manufactured M1 Carbine, that was manufactured in the second contract block of serial numbers (3,212,520-3,250,019). This block was later reassigned to the Saginaw Steering Gear Division of General Motors after the Irwin-Pedersen contract was canceled for unsatisfactory performance. The receiver ring has the standard M1 Carbine markings with the rear stamped: "IRWIN-PEDERSEN/3212895". The barrel is marked "UNDERWOOD/3-43" above the ordnance '"shell & flame" insignia. It has a mix of early and late parts such as an "AI" stamped Type III barrel band late stamped, adjustable rear sight, stamped "IRCO" on the side, a flat "IO" marked Inland bolt, Inland marked trigger group, with an "AOB" marked slide. It is fitted with a low wood walnut stock that is stamped LW in the sling slot, with a boxed "BA/JPL" rebuild cartouche on the left side and a circled "P" proof on the flat of the pistol grip. It is fitted with an early two rivet, unmarked handguard. It comes with a reproduction green canvas sling and a 15-round "BW" marked magazine. The triggerguard bow has a small yellow sticker identifying it as being checked at the M1 Carbine matches at Camp Perry.
