600 is a bit much considering the amount of work involved in restoring it. However, if the person bidding/buying it just wants it as is, the parts alone are worth the 600. If I got it, I would cut away the wings, have new ones made, righty, and fix the headstock. Alot of work, but any RIC under 700-800 is a rare find these days. It might be a good chance to make a quasi-C64 or something.
