Our Assessment: The M1 Carbine was developed and produced after WWII started. Over 6 million were made by a number of U.S. companies to assist with the all out war effort. The M1 Carbine was widely issued to U.S. Military Forces which numbered over 16 million during WWII. The M1 Carbine contributed greatly to U.S. efforts during WWII.
The International Business Machines Corporation (IBM) was one of several contractors who tooled up during WWII to produce M1 Carbines in support of the war effort. IBM only produced about 5.7% of the total number of WWII M1 Carbines. IBM’s low production numbers make IBM M1 Carbines quite desirable.

This IBM M1 Carbine was made back in 1944. The receiver was subcontracted by Auto-Ordnance and is marked “AO” below the serial number. This M1 carbine has been rebuilt. The front sight and grip have been modified. The finish has some issues but should clean up some. This M1 Carbine uses lots of IBM parts. The stock is not made by IBM but an IBM stock can be found on-line or at a gun show. Good luck.
