Manufactured in the mid-1870s, it is estimated that less than 1,000 of these revolvers were manufactured. Many collectors classify these revolvers as a "Secondary Martial" weapon. The revolver is chambered for the 44 caliber Russian centerfire cartridge. The top of the barrel rib is marked "+FOREHAND & WADSWORTH, WORCESTER, MASS. U.S. PAT.D OCT. 22.61 - JUNE 27 '71 - OCT. 28 '73 +". The serial number is found on the butt, hammer, barrel, cylinder, two places on the cylinder pin assembly and both grip panels. It has pinned blade front (replacement) and frame notch rear sights and nicely figured walnut grips.
