This is a circa late 1800’s, Enterprise No. 0, Integral clamp-on, cast iron, hand-crank coffee grinder/ mill. It’s made by Enterprise Mfg. Co. of Philadelphia, U.S.A. It clamps onto a table or counter. It appears to have normal wear in the hopper and turns/cranks easily. It still has the original decals and paint. It is in incredible condition for its age. A nice antique find in original condition!! Thank you for looking.
