Manufactured in 1978, with the included factory letter showing the revolver listed as chambered for .45 Long Colt with 5/12 inch barrel (likely recording error as barrel measures 4 3/4 inches), blue finish, and type of stocks not listed when sent in a lone shipment to D.E.L. Supply in Tewksbury, Massachusetts, on March 8, 1978. A letter from Jim Alaimo of Nutmeg Sports, LLC, dated July 20, 2009, indicates that the revolver (listed by serial number) was subsequently extensively embellished by former U.S. Secret Service member and engraver Paul H. Mobley (1941-1997), who was a part of the security team guarding President Ronald Regan when John Hinkley attempted an assassination on March 30, 1981. After his time with the U.S. Secret Service, Mobley became an engraving student under Colt Master Engraver Ken Hurst, adapting his own style and producing only a small body of work before his passing, with the letter further indicating this example was one of the last that he completed before his passing. Features fixed bad front and notch rear sights, with checker board style patterns on the barrel and front of the frame with floral bordering with punch dot engraving and gold inlaid bands on the barrel, cylinder, frame, and hammer, along with gold inlaid "rampant colt" logos on the recoil shield and frame. The triggerguard is marked "PAUL H. MOBLEY, ENG. '96" under the right panel. Includes a Colt marked oiled walnut display case with yellow felt interior and key.
