If it's complete and cools, and if the body is not damaged from all that scraping etc.... then make him an offer of say 800.... sure you might find one for 800 in a little better shape cosmetically, but if your intention is to restore it, I don't see the difference. Finding a complete working 39 below 800 is hard to do, unless you're in the know, or go to many shows and can strike a deal etc... For the average guy, looking on CL or Ebay, they don't get any cheaper.
