These Derringers were manufactured between 1863 and 1870 with an estimated 6,000 produced. The top of the barrel is marked "O.K" with the serial number "1284" marked on the butt and underside of the barrel. Fitted with a pair of smooth rosewood grips.

Very good, the barrel has a smooth gray patina with some areas of darker coloration. The brass frame has an attractive color with traces of silver under the grips. The grips are both good as refinished with a small chip at the top front of both grips and some scattered minor marks. Mechanically fine.
