An interesting GM product, a M1 Carbine rifle mfg by Saginaw Div. of General Motors, 1943. I’ve had it and other WWII rifles for years, and Yes, it shoots great!
Back in the war years if you had a factory and could work metal or wood you were most likely making weapons or other war materials. International Harvester made M1 Garands (my Garand was made by the original Springfield Armory). The Rock-Ola juke box company made M1 Carbines, as did IBM. Singer (the sewing machine company) made .45 cal 1911 handguns. The list goes on and on……
This rifle is mostly original. Although real hard to photograph, the barrel is stamped “Saginaw” and “General Motors” and the stock has several stampings or “cartouches”. Like most US rifles of the day, the stock is made from Black Walnut.
