Only 1,500 of these Joslyn "Monkey Tail" carbines 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 large pinched blade front sight, ladder rear sight and a left mounted saddle bar and ring. There are no visible ordnance proof or inspection marks. "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, "5E" marked on the left of the breech block and "T4" on the right of the brass barrel band.

Excellent, one of the finest surviving examples, retains 90% plus original brown finish on the barrel with some scattered light scratches, 98% plus vibrant original case colors remain on the lock and hammer, with 60% plus original case colors on the remaining components and smooth gray patina on the balance, with some very light freckling. Crisp markings on the lock and breech block. Brass exhibits an attractive golden aged patina. The stock is also excellent with attractive original raised grains, scattered light scratches and dents, a small crack behind the lock, a professionally repaired section visible at the toe, and distinct edges overall.
