    Early Colt Revolver Among the First Examples of Metallic Cartridge Breech Loading-A Factory Prototype.

    Rare Early Colt Factory Prototype Model 1860 Army Revolver Converted to Metallic Cartridge. Serial no. 170997, .44 rimfire caliber, 8-inch barrel, the top marked: -ADDRESS COL. SAML COLT NEW-YORK U.S. AMERICA. Blued finish. In-the-white six-shot breech-loading cylinder. Experimental conversion ring. Varnished walnut grips.

    The breech loading conversion represents a first departure from the front-loading Thuer conversions. One chamber of No. 170997 was countersunk to accommodate the cartridge's rimmed breech. That countersunk chamber is considered to have been an experimental procedure, abandoned when realizing that to countersink each chamber was not possible, due to the overlapping of each cartridge rim and therefore each cartridge's chamber...thus, first, the circumference of the cylinder had to be enlarged.

    Serial no 170997 on barrel, frame, backstrap and triggerguard with 0997 on wedge and bottom of the cylinder pin. Cylinder marked: COLTS PATENT No. Left side of frame with: COLTS PATENT. Roll marking on the cylinder of the standard Naval Engagement scene. Inspector's initial A on breech of barrel. Inspector's letter B on face of recoil shield.

    Hammer with experimental rimfire firing pin.

    Sold together with Letter of Authentication by R.L.Wilson documenting the details of this gun as a prototype for the Colt Single Action Army. Included in the report is a copy of Colt Factory ledger's "List of Firearms Collection in the Colt's Company's Museum" circa 1878 which lists this lot by serial number.

    Condition: Fine.
