.30 Carbine. 18" barrel. SN: 5240741. Parkerized and blue finish, walnut stock and handguard. Semi-automatic magazine fed military carbine. Rear of receiver marked INLAND DIV over the serial number. Chamber marked US CARBINE/CAL. 30 M1. Barrel marked INLAND MFG. DIV./GENERAL MOTORS/5-44. Barrel, left side of chamber and bolt with British proof marks. Stock with .85" {Ordnance Wheel} inspection cartouche on obverse butt, an IO in the sling cut out on the reverse and a Y on the bottom of the pistol grip. Four-rivet handguard marked IO on the interior edge as well. Component details include a rounded top blued bolt, an IR CO marked Type III rear sight, a Type II barrel band, an M marked magazine release, an INLAND marked triggerguard housing and an HI marked hammer. Further disassembly was not performed. Bore erosion measures 1, throat erosion measures 2.5. The carbine includes a K.I. marked Type II magazine, an OD green web sling and oiler. The Type III rear sights started to appear on Inland produced M1 Carbines sometime during June of 1944, although the majority of the production still retained the more readily available Type I sights. As the barrel, receiver and bolt all retain British proof marks, it is likely that this gun remains in its original WWII configuration as it left the factory.
