These multi-shot pinfire revolvers were manufactured in the mid to late 19th century. Chaineux is known to have manufactured revolvers designed to fire up to 20 shots without reloading. This 12-shot example has attractive floral scroll engraving and is marked "J. CHAINEUX INVR BTE" in one of the cylinder flute. Another flute has the serial number. The large cylinder and necessarily long hammer give the revolver a slightly comical appearance. The triangular front sight and hammer notch rear sight are only useful when firing in single action. The grips are checkered, and a lanyard ring is fitted at the bottom of the butt.

Good. The revolver retains 40% of the period dull refinished blue finish, and the small parts remain mostly bright. The grips have some minor marks in the otherwise crisp checkering. The action functions fine, and the markings and engraving patterns are crisp.
