This is an old hand food & meat chopper in heavy cast metal, I am not sure which metal. It is silver tone and slightly oxidized. It is marked Universal on the grinder on the barrel, and "L. F. & C. New Britain, Conn U.S.A." on the handle. That stands for Landers, Frary & Clark. The knob is wood, in excellent shape. Over all it is in very good to excellent condition with all parts and it works.
