Our Assessment: This M1 Carbine was made back in 1943 by the International Business Machines Corporation (IBM). It is 1 part short of being a “Matching” rifle. The unmarked safety is the only non-IBM part on the rifle. The magazine was made by a different manufacturer but can easily be swapped out with an IBM mag. This IBM M1 Carbine has some finish issues on the metal but should clean up a bit. It will add to your WWII collection.
