This revolver was manufactured in 1853 and has fine Germanic scroll engraving on the rear half of the barrel, all of both sides of the frame, and on the grip frame. The hammer has the wolf head motif. The engraving is clearly that of Gustave Young or one of the top engravers in his shop. The barrel has a small post front sight and "Saml Colt" in hand engraved Gothic script. The left side of the frame has "COLTS/PATENT" engraved instead of stamped. The matching serial number is on the bottom of the barrel, frame, trigger guard, and butt and the side of the cylinder. Partial matching serial numbers are stamped on the wedge and cylinder pin and written in ink on the grip within the back strap inlet. The revolver was updated in the period for use with centerfire cartridges by removing the loading lever, cutting off the rear section of the cylinder, fashioning a removable cylinder breech plate, and fitting a firing pin on the nose of the hammer. The work was evidently done by a capable gunsmith and likely served to keep this attractive revolver serviceable into the late 19th century. This revolver is listed by serial number and described in P.L Shumaker's "Colt's Variations of the Old Model Pocket Pistol, 1848-1872" on pages 57-58.
