I have a 16 ga. with "Hunter Arms Co."-top line and "Fulton New York"-2nd line stamped on the rear of the sighting rib. Both barrels have "armor steel" stamped on the underside and nothing else other than the serial number, which is 64870 OO. When I checked the serial number the gun was made in either 1909 or 1924. Does anyone know how to find out which one it is?
