Our Assessment: This M1 Carbine was made back in 1943 by the International Business Machines Corporation (IBM). After WWII it served for a U.S. friendly country and was eventually imported back into the U.S. for sales to the civilian market. It has been rebuilt using a mix of USGI parts including a Springfield Armory barrel and a High Standard operating slide. We usually don’t see these post WWII parts on M1 Carbines. This IBM M1 will add to your Military or WWII collection and should be a ton of fun to shoot. Good luck.
