In 1865 and 1866, 4,000 Colt Model 1851 Navy revolvers were manufactured in Hartford, shipped to and proofed in London, and then finally inspected by Enfield, who stamped the grips with their cartouche. Some are believed to have gone to New Zealand and Canada rather than Egypt. This revolver was manufactured in 1865 and has standard markings and features for the era as well as London proofmarks, an Enfield cartouche ("R [crown] M" and "Enfield" around an inspector's mark) on the left side of the grip. All visible numbers are matching. A very scarce variation of a Colt Model 1851 Navy revolver!

Fine, retains 40% bright original blue finish on the barrel and 25% of the original case colors on the frame. Silver plating in sheltered areas with the balance a smooth brown patina and attractive antique patina on the brass. The grip is also fine with much of the original varnish, minor dings and scratches throughout, hammering marks on the butts (including the butt of the back strap), and a clearly visible cartouche. Mechanically excellent.
