The U.S. Navy purchased 4,300 Whitney Navy revolvers during the Civil War, with a total of roughly 33,000 of 1st and 2nd Model Navy revolvers manufactured by Whitney in the late 1850s to early 1860s in various configurations. This 4th Type falls in the correct serial range of 15000-25000. Matching serial number on the bottom of the barrel, loading lever, cylinder pin, rear of the cylinder, and back of the grips. "E. WHITNEY/N. HAVEN" marking on the top of the barrel at the breech. Roll stamped cylinder scene of an eagle, lion, naval engagement, and shield bearing rib with "WHITNEYVILLE". "P/J.R.G." inspectors stamp on the cylinder and "U.S./anchor" stamps on the barrel.

Very good, retaining traces of the original blue finish in sheltered areas with the balance mostly a smooth grey patina, a few scattered patches of light pitting, and an attractive antique patina on the brass trigger guard. The grips are fine with a few scattered minor dings. Mechanically excellent.
