Only 1,500 of these Joslyn "Monkey Tail" carbines, invented by Benjamin F. Joslyn, are estimated to have been manufactured by A. H. Waters of Millbury, Massachusetts, in 1855 and 1856 and were the last firearms manufactured by Asa H. Waters. The Waters family had been involved in U.S. martial arms contracts since at least the 1808 contract muskets. These Joslyn carbines are known to have been issued to the 2nd, 3rd, 4th, and 6th Ohio Cavalry regiments in limited numbers. Features a left mounted saddle bar and ring. "1070" marked on the left of the breech block. Joslyn patent markings have been removed (filed off) from the top of the "monkey tail" lever.

Good, with bright polished exposed iron surfaces, with some areas of freckling, old applied brown finish visible above mild pitting in the protected areas of the breech block and on top of the breech, and a replacement soldered front sight and replacement rear sight. The refinished stock is also good, with scattered scratches and dents, a repaired crack on the left of the wrist, a minor crack behind the lock, some mild cracks around the buttplate, a filled in hole on the bottom of the buttstock, and a mild chip at the toe. Mechanically fine.
