This early 1850s pistol is based on William W. Marston's patent no. 7,443 from June 18, 1850, for a piston breech firearms design. It has a six-groove rifled, octagon barrel with a brass post front sight, "W.W. MARSTON/PATENTED 1850" and "NEW-YORK" stamped on the top flat, "CAST STEEL" on the upper right flat, and the serial number on the bottom. The serial number is also repeated on the bottom of the brass frame at the breech, on the butt under the left grip, and handwritten on the back of the grips. The frame and hammer have scroll engraving.

Very good with period reblued finish mixed with dark patina on the iron, attractively aged patina on the brass frame, minor oxidation/pitting, and mild overall wear. The refinished grips are good with a repaired crack in each panel and mild scratches. Mechanically fine.
