I bought a Winchester Model 12 for $100.00. It was made in 1918 (short chamber) and looks pretty tired. It's missing the Cartridge Cut Off, Ejector, and pin/spring that locks the magazine tube. The barrel has been cut to about 24" and it has a slight bulge about 1" from the muzzle. I'd like to get it working but I think I'm going to be in too deep when I get it finished. I'd be willing to sink $200.00 into it but I don't know if it would shoot even if I had the parts. My original thought was to make it into a Police/Prison Guard type gun with a 20" barrel. Should I just part it out?
