I have a M-1 carbine manufactured by IBM Corp. in 1943. I would like to find out at which IBM factory these were made.. IBM had factories in new York state in Rochester, Endicott, Poukeepsie and maybe more.

According to Bruce Canfield's book A Collector's Guide to the M1 Garand and the M1 Carbine, IBM carbines were made in Poughkeepsie.
