Approximately 3,500 Joslyn Model 1862 carbines were made, 2,200 of which the U.S. Government purchased. The lock plate is marked "JOSLYN FIRE ARMS Co/STONINGTON/CONN.", and the breech block is marked with the 1861 and 1862 patent dates. Hook type breechblock latch, pinched blade front and three leaf rear sight graduated up to 500 yards. Serial number "3351" marked on the upper tang and underside of the barrel at the breech, and "1925" on the breech block. "F.D.L" inspection initials marked on the left breech of the barrel. Two boxed script inspection cartouches stamped on the left flat above the saddle bar.

Very fine, retains 90% original dull blue finish on the barrel, 90% vivid original case colors concentrated on the breech block, upper tang and sideplate, with strong traces of case colors on the lock and hammer turned to a mostly smooth gray patina. Brass exhibits a bright patina underneath a light coating of old varnish. Stock is fine as lightly sanded and re-oiled with some scattered light dings and handling marks, a few small hairline cracks visible on the right ahead of the buttplate, and lightly visible cartouches. Mechanically excellent.
