The barrel has the Parisian retailer marking "Fnx pax Gastinne Renette" stamped upside down on the left side and "Paris" on the right side. The dovetail blade front sight and "U" notch rear sight on the top strap are period additions to meet the demands of the day. The revolver is cut for a non-factory shoulder stock (stock not included) and has been re-chambered in .44 S&W Russian, a more period popular caliber than the original .44 S&W American chambering. As S&W historian Roy Jinks noted in the accompanying factory letter, "I would agree that the hole in the top of the back strap could be for a shoulder stock. Gastinne Renette employed some of the best gunsmiths in France and they could do all types of work, including re-chambering to .44 S&W Russian caliber." The sights were also likely added by a gunsmith employed by Renette. The factory letter confirms the revolver was shipped on June 27, 1873 and delivered to M.W. Robinson of New York City with an 8 inch barrel, nickel finish, and smooth walnut stocks. The revolver has the one-line S&W address/patent dates barrel rib marking, matching assembly numbers on the grip frame, cylinder, barrel, and barrel latch, and right grip panel numbered to gun.
