That is a Model One pickup. The carcass has been carved like a PRS but there are enough similarities to an original 59/60 EB-0 that I think it is. Odd that the seller mentions other less important mods while ignoring the Model One and the carving.
Yeah, the price is nuts. No one who knows anything about the originals would pay anywhere remotely near that. I agree with nofi, $450 is more like it. This one has no vintage vibe.
