The guy who I bought AUTF's Marshall from a few weeks ago was a roadie back in the 80s for a well-known American rock band. During that time, he met and became friends with a bunch of other bands and musicians.
He told me that he went to a guitar shop back then with Joe Walsh, who was looking to sell one of his 1970s Les Pauls. The shop lowballed Joe, who then offered the LP to the roadie for the same price. The guy bought it and still has it, but he's not playing much anymore and has been selling off a lot of his gear.
I have no idea how much he would want for it, but I think he would sell it. He said he's thought about calling up Joe to see if he wants to buy back his Les Paul, but said it's been years since he talked to him and figured Joe has all the Les Pauls he needs.
Provenance might be an issue since it was a cash and a handshake deal made before vintage guitars were a thing. But if anyone is interested, I can ask the guy for a price and some pics.
