Our Assessment: This is an Inland Division M1 Carbine, manufactured in late 1943 and fitted with an Inland-marked barrel dated 10-43. The barrel was produced by the Brown-Lipe-Chaplin division of General Motors, which manufactured approximately 90,000 barrels in 1943 for “free issue” to prime contractors that did not produce their own barrels. These B.I.-marked barrels are regarded as some of the highest-quality wartime carbine barrels. Inland utilized these barrels internally as well, particularly during high-demand periods of 1943 production.

This example has been installed in a reproduction M1A1 paratrooper folding stock, giving it the appearance of the iconic airborne configuration used by U.S. paratroopers in WWII. While the stock is not original, it offers a visually striking and historically inspired presentation of the carbine. The rifle retains the core Inland receiver and barrel combination, both of which are prized by collectors for their historical relevance and production quality. It serves as a tribute to the robust output of General Motors’ wartime subsidiaries and their contribution to arming American troops.
