Reportedly 3,000 Army Model revolvers were manufactured in 1861 and 1862 by the Joslyn Firearms Company in Stonington, Connecticut. The Joslyn is one of the scarcest of all the revolvers used by the Union Army and Navy. 1,100 Joslyns were purchased on the open market and primarily issued to Ohio units including the 5th and 6th Ohio Cavalry. Dovetailed blade front sight, a sighting groove in the top strap. "B.F. JOSLYN/PATD, MAY 4TH 1858." on top of the barrel at the breech. The full serial number is marked on the butt, bottom of the barrel, and partially on the loading lever. There is also a "B" marked on the loading lever, which is likely an ordnance inspector mark.

Good, showing mostly a smooth grey patina with some scattered patches of light pitting and a crack near the cylinder pin. The grips are also good with some scattered minor handling marks, a few hairline age cracks, and mostly well-defined checkering. The cylinder does not turn or lockup when the hammer is cocked, otherwise mechanically fine.
