Pettengill Army Model Double Action revolver manufactured by Rodgers & Spencer & Co., of Willow Dale, New York. There were approximately 3,400 total Pettengill Army revolvers manufactured, with this example included as one of 2,000 purchased by the U.S. Ordnance Department between October 1862-January 1863. The Pettengill double-action revolver is known for fouling internal parts after several discharges, which made it nearly impossible to fire. Pettengill Army revolvers were issued in quantity to the 3rd Michigan Volunteer Cavalry and in small numbers to several other Midwestern cavalry regiments. This revolver has a high polish blue finish on the frame, octagon barrel and six-shot cylinder. The loading lever is color casehardened. The two-piece walnut grip is oil finished. The top strap is marked "PETTENGILLS/PATENT 1856/PATD JULY 22 1856/& JULY 27 1858". The serial number "4110" is stamped on the side of the cylinder, inside of the trigger guard, underside of both grips, and on the butt. "W" sub-inspection mark on the left side of the loading lever, "WW" on the left side of the barrel and frame. Boxed script "NW" (Nathaniel Whiting) cartouche on the left side grip panel.

Exceptionally fine. The revolver retains 60% plus bright original blue finish mixed with smooth mottled brown patina. There are a few mild scratches on the left side frame and on the cylinder and some handling marks. The grips are very fine with a number of circular dings on the bottom flats and high left, chips along the bottom edges, and handling marks. The action functions but the cylinder returns to the same position after cycling.
