Around 30,000 of these revolvers were manufactured in approximately 1864-1870. They utilize front loaded "teat-fire" cartridges designed by Daniel Moore as a work around of the Rollin White patent. Fifty of these rare cartridges are included in the case which is inscribed "Presented to/S.L.M." on the lid escutcheon. The revolver has a full silver plated finish, attractive scroll engraving, the standard round blade and hammer groove sights, "MOORE'S PATENT FIRE ARMS Co. BROOKLYN, N.Y." on top of the barrel, "D. WILLIAMSON'S PATENT JANUARY 5. 1864" on the rear edge of the cylinder, "PAT/APR 26/1863" on the right side of the barrel lug under the loading gate, "U" on the right side of the grip frame, and matching serial numbers marked on the bottom of the barrel (1099), left side of the grip frame (K99), and back of the grips (99).
