This is a First Model 1860 Richards Conversion revolver with nickel-plated finish, one-piece antique ivory grip and Germanic scroll engraving on a punch-dot background. The engraving appears to have been executed by master engraver L. D. Nimschke or his shop for Schuyler, Hartley and Graham of New York City. Schuyler, Hartley and Graham employed L.D. Nimschke to embellish most of the few engraved Model 1860 Richards Conversion revolvers. The top of the barrel is roll-stamped with the legend: "-ADDRESS COL. SAML COLT NEW-YORK U.S. AMERICA-" in an engraved panel with wavy line and dot borders. The early "COLTS/PATENT" marking on the left side of the frame is enclosed in an engraved oval. The forward portion of the cylinder is roll-stamped with the Texas Navy battle scene and the rear of the cylinder and the conversion ring have zigzag and punch-dot engraving. The top and sides of the back strap have sunburst engraving with a wavy line and dot border and the remainder of the back strap and butt are outlined with wavy zigzag engraving. The serial number is located on the bottom of the barrel lug, frame, trigger guard and back strap. The cylinder is stamped with the partial serial number "9533". All of the visible serial numbers match. The inside of the loading gate is assembly numbered "172". The revolver has an internal loading gate spring, cross-hatched ejector head and bordered and underlined hammer spur knurl. The revolver is complete with a russet leather open top California pattern holster. The undecorated, form fitting holster has a single recurve at the throat for the trigger guard and a belt loop attached by three copper rivets.
