That was my grandpas 22lr its a lever action single shot.
Nice! I bet it's a nail driver. Is it a winchester? A buddy of mine has a winchester single shot .22LR lever he got from his grandpa. It's a take down( barrel and forarm screw in to the chamber ). He still has the hard case( looks like a thin suit case) where it's stored in the two pieces. I've only seen it once. Beautiful gun.
