Manufactured by Ithaca for the United States Air Force as a survival weapon, this is the original version with the 14 inch barrels, that has been correctly registered with the BATFE as an "AOW", (Any Other Weapon). Marked on the left side of the receiver "U.S.A.F. PROPERTY/138032/ RIFLE-SHOTGUN. SURVIVAL/CAL. .22/410, M6". The right side is marked "ITHACA GUN CO. INC. ITHACA N.Y.", with the crossed cannon ordnance stamp and "PA". Markings for Three Dog Gunsmithing have been added to the underside. These rifles have a break open action with a fixed front and two-position flip rear sight. It has a squeeze type trigger with a stamped, skeletonized stock with a cartridge block located inside the stock. The comb area lifts up to show that the spare cartridge block holds nine .22 rifle cartridges and four .410 shotgun shells. A green paracord wrap has been applied to the barrels, with a light camouflage pattern paracord sling; consignor statements describe this as an "in theater" modification.
