Serial # 51351, 32 rim fire, 3 1/2 inch barrel, very good five groove bore with areas of light erosion. This revolver was built from 1868 to 1875 and it still looks pretty good. The metal surfaces have developed a dark grey patina with traces of blue in protected areas. Hinge is loose and case removal pin is missing. The grips fit perfectly, right side has a chip at bottom. Gun still works although cylinder stop is a little weak. This would make a great project gun. Free shipping.
