This carbine has the "Type I" Civil War-era features which include 20-inch round barrel chambered for the .46 rimfire cartridge, short 7 1/2-inch forearm and small receiver. The carbine has a steel dovetail mounted front sight blade and two-leaf folding rear sight. A sling bar and ring are mounted on the left side of the receiver. The upper receiver tang is roll-stamped: "REMINGTON'S. ILION, N.Y./PAT. DEC. 23. 1863, MAY 3 & NOV. 16. 1864". It is estimated that less than 1,000 of these saddle ring carbines were assembled from remaining parts in various configurations after the completion of both military contracts.
