The serial number dates this revolver to 1861, and it was later converted at the factory for metallic cartridges in the late 1860s or the 1870s. It is not one of the standard conversions and is pictured and described on pages 376-377 of "A Study of Colt Conversions and Other Percussion Revolvers" by McDowell where it is identified as a "Tool Room" conversion. It may be one-of-a-kind. It has attributes of both the Richards conversions and some of the Pocket Model conversions. It has a brass post front sight, "-ADDRESS SAML COLT HARTFORD CT.-" on the top of the barrel, re-contoured barrel lug with filled rammer slots, unmarked cylinder with rectangular stops and slightly recessed chambers at the rear, unmarked smooth cylinder arbor pin, permanently attached conversion breech plate with integral notch rear sight and centerfire firing pin, modified hammer, "COLTS/PATENT" on the left side of the frame, a small "G" on the left side of the trigger guard, and matching serial numbers on the barrel, frame, and grip straps and hand-written in the back strap mortise of the grip.

Rating Definition:

Good as period modified with traces of original finish and otherwise dark patina and slight oxidation on the barrel, frame, and cylinder; 25% original silver plating concentrated around the trigger guard and under the grip, aged patinas on the silver and exposed brass, and general mild wear. Some of the markings are faded. The grip is fair and has chipping at the heel and toe, some dings and scratches, and mild edge wear. Mechanically fine. This is a very interesting piece and will certainly be a great addition to any collection of antique Colts.
