Ultra rare Richards Mason Conversion of the Colt Model 1860 Army Revolver s/n 6033, with 8 inch barrel, manufactured circa 1877-1878. Total produced is estimated at about 1,200. Pictured and discussed on page 206-7 of “Colt Conversions” by R. Bruce McDowell.
It is chambered in obsolete 44 Colt centerfire, with a 6-shot rebated cylinder and 8 inch round barrel, with attached ejector rod. It has smaller lug area than the Richards Model.
Blued barrel, cylinder, ejector housing and back-strap with case-coloured frame, breechplate and hammer. The large brass trigger-guard is silver-plated. Complimented with one-piece army size walnut grips. The cylinder gate assembly number is “26”
Serial numbered within the recognized range of the Richards Mason running from 5800 to about 7900. The barrel address reads “COLT’S PT. F.A. MFG. Co HARTFORD, CT. U.S.A.” On the left side of the frame are 1871 and 1872 patent dates. 44 CAL is stamped on the left shoulder of the trigger guard strap. Cylinder roll depicts the naval engagement scene.
Identifying characteristics allowing for quick identification of this model are: Breechplate without integral rear sight, cut away at top to allow for the hammer to strike the cartridge, no projecting front rim on the conversion plate (as on the Richards Model), and the special barrel made for the Richards Mason conversions.
Very fine condition, all visible numbers matching including the cylinder (033), with strong traces of original finish and good working action. A very desirable example of a rare Richards Mason Army conversion.
