Approximately 8,000 Model 1864 Joslyn breech loading carbines were purchased by the Ordnance Department during the Civil War. Pinched blade front and three folding leaf rear sights. It has the correct hooded firing pin that distinguishes the Model 1864 carbine from the Model 1862 carbine. Matching serial number "11729" marked on the breechblock and upper tang. Two boxed script "FDL" inspection cartouches stamped on the left stock flat above the saddle ring bar, with small "F.D.L" initials stamped on the left of the breech and top of the stock ahead of the buttplate, and a small anchor is stamped on the bottom of the stock ahead of the trigger guard. "US" marked buttplate tang.

Very good plus, retains 20% faded original blue finish on the barrel with smooth gray and brown patina on the balance of the iron surfaces with some scattered light freckling and sharp markings and edges. Stock is very fine, with scattered light scratches and dings and defined edges. Mechanically excellent.
