Ivers Johnson Champion Help needed
My father In-Law was given a Ivers Johnson Champion 12GA. break open shot gun.The only serial number I can find is "GXUI" behind the trigger guard, on the side of the receiver it says " IVER JOHNSON'S ARM & CYCLE SHOP Fitchburg Mass USA. The top of the barrel says "12Guage full choke, barrel and lug forged in one."
Looking for approx manufacture date?
What type of ammo can be used in it?
