Offered in this lot we have a Colt Model 1861 Navy Richard-Mason Conversion revolver, chambered for .38 Center Fire. The 1861 Navy was designed by Samuel Colt, and originally utilized .36 caliber paper wrapped cartridge, fired via ball & cap. It was in 1869 when Rollin White's patent for rear loading metallic cartridges expired, and a number of Colt 1861 Navy's and its forerunner, the Colt 1851 Navy were converted or newly made to fire .38 Rim Fire or centerfire cartridges. This example shows the trademark details of a Richard-Mason conversion, starting with the streamlined barrel with a plugged loading lever hole, loading gate secured by a flat spring secured to the frame, a breech plate with a top cut-out with no provision for a rear sight, and a ejector assembly secured by a screw in the left side of the barrel. This firearm features a 5 1/4" long round barrel, six shot brass plated cylinder, walnut grips, nickel plated frame and barrel, and brass trigger guard. Additionally, the revolver is marked across the side of the frame showing two-line patent dates "PAT. JULY. 25. 1971." over "PAT. JULY. 2. 1872." on the left side of the frame. The pistol shows two pairs of matching serial numbers "1264" on the bottom of the grip, and trigger assembly, with "28815" on the frame and barrel. Overall, the revolver shows good condition. Aesthetically, the revolver shows sharp roll stamps, and bright finish. Mechanically, the revolver has a tight action, with tight cylinder lock-up, slight miss timing on the cylinder, and a fair bore. Serial Number: 1264. This firearm qualifies as an Antique, and does not require FFL Transfer or NICS Background Check.
