Approximately 8,000 Model 1864 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 pinched blade front and three folding leaf rear sights. It has the correct hooded firing pin that distinguishes the Model 1864 Carbine from the brass mounted Model 1862 carbine. "F.D.L" inspection initials marked on the left of the barrel and on top of the stock ahead of the buttplate tang. Matching serial number "4342" on the breechblock and upper tang. Two crisp boxed script "FDL" inspection cartouches stamped on the left stock flat above the saddle ring bar. "US" marked buttplate tang.

Very fine, retains 90% original blue finish on the barrel, and 70% original case colors on the lock and breech area with smooth gray patina on the balance. Sharp markings and edges in the metal overall. Stock is very fine as lightly re-oiled, with a patch of dings concentrated on the left of the forend and clear cartouches. Mechanically excellent.
