Manufactured circa 1860 to 1868, this is an example of one of the approximately 4,400 2nd Issue revolvers that were marked "2D. QUALITY" due to a slight casting flaw during manufacture. This revolver is marked "2D QUALITY" on both sides of the rear of the barrel. The top of the barrel is marked with the one line address, the serial number is marked on the butt, the cylinder is marked with the patent dates and the back of the barrel lug is marked "JJO". The barrel and cylinder are finished blue, casehardened hammer and trigger, and the frame is silver-plated brass. Fitted with smooth two-piece rosewood grips.

Fine. The barrel retains 30% original blue finish strongest in the protected areas, with the balance thinning to a mottled gray patina and showing some isolated pin prick pitting around the breech. The cylinder has a gray patina with overall minor pitting. The frame retains 95% original silver plating, which is darkening with age, with some brass beginning to become exposed on high edges and showing some minor dings and scratches. The grips are fine and may have an additional coat of varnish applied some time ago, showing some minor wear on the lower edges and overall some scattered minor dents and dings. Overall a nice solid example of a rare variation of a Smith & Wesson 1st model 2nd issue revolver.
