This old Cast Iron Food Grinder is marked 20 ECONOMY Made in U.S.A. It has the Keystone Boyertown logo with 20 inside. Later models were marked with the Company name etc. It measures approx. 9 inches tall with the counter table clamp screwed in. It has a manual turning wood handle. It has only one size grinder plate. It is well used with rust, tarnish, missing plating and stains. It would be a good kitchen decorating piece or usable with some more cleaning.
