My younger brother has one of these gems, also a hand-me-down from our grandfather. It was the first trigger I ever pulled. Last one I saw at a gun show was priced over $300.
I'd appreciate any advice on how to fix the rear sight, the screw that holds the rear sight down has become stripped, so for now the gun lives in the closet. Still cycles just fine though.
I know it accounted for hundreds of rabbits, yard varmints, and a handful of deer over the years though.
