This model was manufactured between 1861 and 1874, with this particular revolver having been made during the Civil War. Many of these were sold commercially and used as personal side arms by Civil War soldiers, as it was the only weapon able to fire self-contained cartridges and be easily carried as a backup by soldiers going off to war. The top of the barrel rib is marked "SMITH & WESSON SPRINGFIELD, MASS." and the serial number is marked on the butt. German silver blade fixed front sight, 6-shot, unfluted cylinder is roll engraved with the S&W 1855, 1859 and 1860 patent dates around the center. The frame has a spur trigger and three-pin top strap. Fitted with varnished smooth two piece rosewood grips.
