Spencer Model 1865 carbines were serial numbered in the approximate range 1-23000 and manufactured circa 1865-1866. The top of the receiver has the four-line address/patent date and Burnside Rifle Co. marking along with "MODEL/1865". The left of the stock has two crisp boxed script inspection cartouches. It has a ladder rear sight graduated to 900 yards, and saddle ring mounted on the left of the stock. Many of these late Spencer carbines were used during Reconstruction and in the Indian Wars before the Springfield Trapdoors were widely issued, with plenty of others seeing use out West well into the end of the 19th century.

Exceptionally fine, retains 80% original blue finish on the barrel, 75% plus vivid original case colors remain on the frame and components with some scattered light to moderate areas of freckling. Markings and edges in the metal are distinct. Wood is also very fine with defined edges, scattered dents and scuffs, and crisp cartouches. Mechanically excellent. This exceptional Spencer-Burnside carbine would make a fine addition to any U.S. martial collection!
