Manufactured between 1856-1859, the Fourth Model reportedly had a total production of only approximately 50 (per Flayderman's Guide). The Savage & North Fourth Model "Figure 8" revolver is nearly identical to the Third Model, but is distinguished by its iron frame. The loading lever housing has the H.S. North patent date marking. The top of the frame is marked "E. SAVAGE MIDDLETOWN, CT. /H.S.NORTH.PATENTED.JUNE.17th 1856". The six-shot revolver features the unusual ring-trigger action in which the ring trigger revolves the cylinder and cocks the hammer. It is fired with a second trigger which fits in the curved arm of the lower trigger. Features a brass cone front sight and a notched lug rear sight dovetailed into the top of the frame. Number "31" is visible on the bottom of the loading lever, side of the hammer (requires removal of the sideplate for viewing), front surface of the sideplate, and on the underside of both grip panels. These early Savage revolvers were redesigned and became the more widely used Savage Navy model manufactured during the Civil War and purchased by the U.S. government.

Good, with a mix of gray and brown patina overall with scattered light to mild pitting and wear. The grips are also good as sanded and re-oiled, with mild wear, scattered dents and scratches, a few small chips, cracks and a few spliced repaired sections visible. The hammer occasionally will not remain in full cock when using the cocking lever, otherwise mechanically fine.
