Here are three double wheeled Enterprise coffee grinders. The first one is a number 7, the second is a number 3, and the third is a number 2. The #2 grinder was mounted on a stand in front of a lamp. The seller said it collected too much dust and sold it to me for $15.00.
The last coffee grinder is a Landis, Ferry and Clark. Its equipped with a cast iron coffee tray. They all grind coffee beans well and we use them on occasion. ....hotairfan
