This rifle have been standing at my grandfathers house since i was a kid and i decided to figure out what kind of rifle it is.I managed to find these proof marks on the barrel and i know what some of them mean but not all, maybe someone here knows more.
Proof marks can be frustrating to look up sometimes. You can start here and i spotted a couple quickly. Appears to be a black powder gun of sorts and the two proof marks i see don't give much to narrow down a date. Early 1800's to the late 1960's. I'm sure other marks can narrow down those dates more.
