Original Colt M1855 Sidehammer Model 7A Pocket Percussion .31 cal Revolver. These guns were produced form 1855 -1870. This example is post war and was made in 1868. Has a great overall patina with some original finish. The walnut grips are in great shape. Has the premium 4 1/2" barrel with New York Address. The mechanics are not fully functional as often found with these guns. The hammer will click and releases with the trigger but the cylinder does not rotate. A great gun for the money!
