Only 1,500 of these Joslyn "Monkey Tail" carbines are estimated to have been manufactured by Asa H. Waters of Millbury, Massachusetts between 1855-1856, 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 large pinched blade front sight, ladder rear sight, and a left mounted saddle bar and ring. "A.H. WATERS & Co/MILBURY MASS" marked on the lock, "PATd BY/B.F.JOSLYN./AUG.23.1855" marked on top of the breech block in reference to inventor Benjamin F. Joslyn. "G1" marked on the right of the brass barrel band.

Exceptionally fine, retains 75% original brown finish on the barrel, 60% plus original case colors strongest on the breech block with a smooth gray appearance on the lock and hammer, with some scattered light freckling, some light corrosion on the breech ring latch, bright golden patina on the brass, and sharp markings on the lock and breech block. Stock is very fine with attractive original raised grains, numerous scattered light scratches and dents, a few small chips, and distinct edges overall. Mechanically excellent. An exceptional example of a very scarce Joslyn "Monkey Tail" carbine that would make an excellent addition to any U.S. martial arms collection!
