12/15/20 - This is a scarce M1 Carbine as produced in 1944 by I.B.M in New York. Only 5.7 percent of total M1 Carbine production during the war was done by IBM. Many correct IBM parts, including JL-B marked stock. Handguard is in Inland replacement. A few other small parts aren't correct, including the front sight which is 'N' marked. Minty bore. Excellent stock, minor dings and nicks.
