This is an example of a Colt 1860 Army revolver that has been factory fitted with a Richards conversion unit. This revolver is a Second Model conversion, a transition type between the Richards and Richards-Mason models. These revolvers are found in the 170000-200000 serial number range. This type of conversion was performed by supplying a new cylinder, for the Colt 44 CF cartridge, fitting it with a new cylinder ring in front of the recoil shield and installing a new loading gate on the frame with an external spring. The loading lever has been replaced with an ejector housing on the right side of the barrel lug, which has the cross-hatched ejector head. The hammer has a firing pin added. The top of the barrel is marked "-ADDRESS COL. SAML COLT NEW-YORK U.S. AMERICA-," and the left side of the frame is marked the 1871 and 1872 patent dates. The cylinder is roll engraved with the Texas Navy scene and "COLT'S PATENT NO. 4570." Matching numbers are found on the barrel, frame, trigger guard, back strap and cylinder. The loading gate has the assembly number "1078" and was remarked with the number "4570." The wedge is unmarked. The revolver has a three-screw frame, brass trigger guard, iron back strap and one-piece varnished walnut grip.

Good. The revolver has a smooth brown-gray patina with traces of original blue finish and case colors in and around the protected areas. The trigger guard retains traces of original silver plating in the protected areas. The worn chattered grip is poor with a couple missing chips. Mechanically excellent.
