It's made of cast iron with holes to bolt to the bench top; its just a stand with bronze bushings (oil caps on top) for the arbor with a pully in the middle that you hook up to a motor behind. You can put a grinding wheel, wire wheel or buffer on either side. There are tool rests, but no wheel guards of any kind. I've got one and want to put it on ebay but haven't the foggiest idea what they are called. I've Googled and searched on Ebay every which way but can't find another one to compare it to. What are these things called? I'm sure its an antique.
