This mechanism was stored in my barn and the owner no longer wants it. It is not rusty and it looks like most of the parts are there, although it may have had a large, multi-grooved pulley at one time. The large wheel has a diameter of over 5' and the beveled gear has a diameter of about 3". I have no idea of its history or the type of business it was used in. Obviously, this is a buyer pickup. I'll be glad to send specific pictures if requested.
