This shotgun was designed for use by the U.S. Army Air Corp. during World War II for skeet shooting in order to train aerial gunners in the art of leading a flying target. "U.S." and flaming bomb proof marked on the top breech area of the barrel and left of the receiver, and "MILITARY FINISH" marked on the left of the receiver. Crossed Ordnance cannons and "FJA" (Frank J. Atwood) inspection cartouche marked on the left of the buttstock. The factory barrel assembly is non-matching numbered "705325" on the bottom, and was likely factory assembled this way during the war, as Remington was utilizing commercial shotguns out of their inventory to fulfill government needs. "XMM" December 1943 date code on the left of the barrel at the breech. It is complete with an original Cutts compensator and Lyman 705 F.C. choke on the barrel, single nickel bead front sight, and 2 3/4 inch chamber. The barrel is correctly without choke markings. Length of pull is 14 inches.
