Marked "PERRIN / & Cie Bte" in tiny letters on the left side of the frame with a sunburst over "PARIS" on the right side and the serial number is marked on the underside of the barrel. The cylinder is marked "1264". The top flats of the breech end of the barrel are inscribed "CCT". Small numbers of these revolvers were imported during the Civil War. Various estimates put the number at about 1000 and they are considered a secondary U.S. Martial piece. They employed an unusual cartridge, unique to this revolver, with an inside primed brass or copper case with a very thick rim around the base. No other cartridge would fit the chamber. This example has no military markings. The cylinder pin is kept in place by the ejector rod which swivels on a collar around the rear of the barrel. Fitted with a one piece walnut grip with a steel buttcap and lanyard ring.
