This truly outstanding Richards-Mason metallic cartridge "conversion" of a Colt Model 1862 Police revolver is pictured on page 161 of "The William M. Locke Collection" by Frank Sellers and is certainly among the finest Colt "conversion" revolvers extant. Only around 6,500 '62 Police/Pocket Navy revolvers were manufactured c. 1873-1875 using a mix of left over and newly manufactured parts. Within this group, there are a variety of variations in barrel length, centerfire versus rimfire, fluted versus non-fluted cylinders, markings, and finish making this revolver especially scarce. It is finished with a high polish blue on the barrel, ejector, and cylinder; niter blue on the screws and trigger, case colors on the hammer and frame, and silver plating on the trigger guard and back strap, and it is fitted with a "piano" varnished walnut grip. The barrel, frame, trigger guard, back strap, and cylinder are all marked with the matching low serial number "112", and the breech plate and loading gate have the assembly number "68". The loading gate is the style without a spring. It features a small brass cone front sight, "ADDRESS COL. SAML COLT NEW-YORK U.S. AMERICA" on top of the barrel, the ejector rod housing fitted on the right, "COLTS/PATENT" on the left side of the frame, and "36 CAL" on the left side of the trigger guard. Provenance: The Williiam Locke Collection and The Mac McCroskie Collection

Excellent. 98% plus of the original silver plating remains, and the silver has a pleasant aged patina. 98% of the vivid, original case colors remain. 90% plus of the original, bright, high polish blue remains. The loss is confined mainly to flaking on the ejector housing and raised portion of the cylinder chambers. Overall, the revolver mostly has minor handling and storage marks. The grip is also excellent and retains nearly all of the original "piano" varnish and has minimal light handling and storage marks mainly on the butt. It remains mechanically excellent. This is a beautiful and outstanding Colt revolver documented as formerly part of one of the most well-respected antique American arms collections, and it is sure to be a proud addition to anyone's collection.
