Approximately 2,200 Model 1862 Joslyn breech loading carbines were purchased by the Ordnance Department. The Joslyn was one of the more widely used carbines during the Civil War. The carbine is equipped with the hook type friction latch breechblock and pinched blade front and three folding leaf rear sights. Inspector initials "E.F" are marked at the breech on the left side of the barrel, and there are two "EF" cartouches on the left stock flat above the saddle ring bar.
