Colt 36 cal percussion. Frame and strap matching serial number 256. Barrel no markings but butchered serial number. Barrel looks totally screwed up and foreign to the gun. The cylinder appears to show Stagecoach scene but hard to tell. Any thoughts would be appreciated. I've had it on a book shelf for years and really haven't paid any attention to it. You guys were such a resource for my Sharps and Spencers I thought I would ask for your help on this one. Colt website has 3 entries for serial number 256 (1) 1851 Navy (2) 1861 Model 1862 Police and Pocket Pistol (3) 1861 Navy with Naval engagement scene. Other than a doorstop, what do I have?
