A fine cased William W. Marston three-barrelled .32 cal Derringer circa 1864-1872

This very nice example made by William W. Marston in New York City, patented May 26, 1857, and improved in 1864,has a brass frame, ivory grips and a German silver front sight. Of the 3,300 made over the eight year production, very few have ivory grips. The case, although of the period, is probably not original.
