Manufactured circa 1861 to 1865, the top barrel flat is marked "D.D. CONE WASHINGTON DC" with the matching serial number on the bottom of the barrel, on the butt and stamped inside each grip panel. Dennis Cone was a patent attorney and may have gotten his payment for services in these revolvers. The front sight is a brass blade set directly in top of the barrel, the rear sight is a groove in the frame. Matching serial number on the barrel, butt, cylinder and inside of both grip panels. Blue barrel and cylinder, and silver plated iron frame with a casehardened hammer. Fitted with smooth two piece varnished grips. Complete in a walnut case with red velvet lining. The case has two compartments and a cartridge block for 24 rounds.

Excellent. The barrel retains 85% original bright high polish blue finish with some thinning due to cleaning, high edge wear and some spotting. The cylinder retains 95% bright original finish with some thinning to brown and a couple spots of minor oxidation. The frame retains 80% plus original silver with the balance having a silver gray patina. The hammer retains most of the original vivid case colors. The grips are excellent with 99% original varnish, some very minor lower edge wear a few small dings on the bottoms and a few minor dents and handling marks. Crisp markings. Excellent action. The case is very fine with a number of minor scratches and scuffs on the outside as well as a minor 3" crack in the lid. The lining is also very fine, totally original with some fraying on the edges and some contact wear.
