Built by Inland Division of General Motors in 1942, this M1 Carbine represents early wartime production that later went through Rock Island Arsenal for overhaul, as indicated by the RIA/EB stamp on the right buttstock. The rebuild provenance places it squarely within the well-documented arsenal upgrade programs that standardized features and ensured continued serviceability.
The configuration shows key arsenal updates: a Type III barrel band with bayonet lug that accepts the M4 bayonet, an adjustable windage-knob aperture rear sight, a round bolt, and a rotary safety. The front sight is wing-protected and marked "S.A.," noting Springfield Armory manufacture.
Furniture details include a low-wood hardwood stock with an oil finish, a two-rivet wooden handguard, and a checkered steel buttplate. Steel components carry a parkerized finish consistent with arsenal practice, offering a uniform, protective coating across the receiver and other parts.
Chambered in .30 Carbine, it uses the M1 Carbine's short-stroke gas piston, semi-automatic action. The barrel measures 16.25 inches, and the length of pull is 13.25 inches. A USGI web sling is installed, and the stock oiler is fitted in the sling channel, completing a functional, period-appropriate setup.
