That is a good idea. Someone did suggest to re stamp it after sorting the trigger block out. I can defiantly see a S??693. I think there might be a 4 before the 6?
I put it back together, it does shoot. Needs a new seal, a piston keeper screw(there are two screw holes on the piston. One that attaches the seal and the other I believe to be a keeper screw), cocking arm keeper screw and rear sight. I have a spare rear sight base that will fit. Just thinking whether it is worth it to fix up or leave as is....
