This is a fine example of an early production two-digit serialized example of one of the approximately 600 purchased by the U.S. government of the 1,000 Adams Navy Model revolvers manufactured by the Massachusetts Arms Co. in the late 1850s and early 1860s. This example, serial number 24, is bearing oval script inspection cartouches stamped on both sides of the grip. The revolver has the Kerr patent rammer on the left side of the six-inch octagon barrel, .36 caliber five-shot cylinder, safety bar on the right side of the frame, hammer with coarse knurled spur and one-piece, checkered walnut grip with a provision in center of grips presumably for a lanyard. Matching serial number "24" marked on the cylinder and left of the frame, "ADAMS.PATENT/MAY 3D 1853" roll-stamped on the left of the frame, "PATENT/JUNE 3.1856" stamped on the right of the frame, and "1485" stamped on both sides of the grip. Small "A" and "T" Ordnance sub-inspection marks stamped on the major components.

Fine, retains 60% plus original blue finish with smooth brown patina and scattered freckling on the balance, with sharp markings and edges in the metal overall. The grip is also fine with defined checkering, some scattered scratches and nicked checkered panels, a faint cartouche on the left and a crisp cartouche on the right. Mechanically excellent.
