It has blade and notch sights, "CONNECTICUT ARMS & MANF'G Co NAUBUC CONN." on the barrel, "2" on the breech face, "PATENTED OCT. 25. 1864" on the breechblock, "5" on the left side of the back strap, and the matching serial number on the left side at the toe and inside of the left grip panel at the top. A dot pattern box with a cartridge block containing six cartridges is included. Includes the original box.
