Here is a picture of a gun that I received from my uncle's estate. It has CHAMPION on the top of the barrel and under that it says PATD APR 2'01, APR 15'02 PATS. PENDING
On the side it says IVER JOHNSON'S ARMS & CYCLE WORKS FITCHBURG, MASS. U.S.A.
I'm trying to find out some basic info for this gun; the manufacture date, estimated worth, if this is a black powder or modern ammo capable.
