Manufactured from 1864 to 1872 with the majority of production of 3,300 made equipped with the standard 3 inch barrel. German silver blade front sight and barrel latch groove rear sights, with the left side of the frame marked "WM. W. MARSTON / PATENTED / MAY 26. 1857 / NEW YORK CITY / IMPROVED 1864". The three-prong extractor and combination safety switch/barrel selector are on the right side of the frame. Smooth rosewood grips with a square butt. Matching numbers, including the grips.

Good. A mixed brown patina has formed on the barrel group, with a few streaks of light gray along the high spots and scattered spotting. The frame shows an attractive brass patina overall, with dark traces of the original silver in the protected areas. Grips are good, with a mended chip on the rear of the left panel and traces of varnish overall. Action functions, but does not advance counter on right side of frame. Needs work.
