The manufacturer's marking on the left side above the Merwin & Bray agent markings are not clear, but the presence of a serial number below and the caliber suggests it was manufactured by either Dwight, Chapin, & Co. or Ball & Williams in 1863 or 1864. It has a blade front sight, two leaf rear sight graduated out to 500 yards, standard patent and manufacturer markings on the frame, manual ejector below the barrel, and smooth stock and forearm with sling swivels on the barrel band and butt.
