Less than 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 are known to have been issued to the 2nd, 3rd, 4th, and 6th Ohio Cavalry regiments in limited numbers, per "Flayderman's Guide" (9th Edition, 9B-066). These 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. 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. "5S" marked on the left of the breech block, and "X6" on the right of the brass barrel band.

Exceptionally fine, retains 85% plus original blue finish on the barrel with a plum hue, 75% vivid original case colors with a few patches of minor surface freckling, attractive untouched golden aged patina on the brass, and sharp markings on the lock and breech block. Stock is very fine with attractive original raised grain and rich oil finish, some scattered scratches and dents, a few mild scuffs, 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!
