OK, its on its way to me and at a decent discount to the stated price. The guitar shop said: "The pickup was not replaced, the previous owner told me it was asked like that, with lower output than the original. The paint is original. The previous owner was the original owner who bought it new in the 80's. The Q filter works great. Everything is in good condition. The double trussrod is working properly. He also said the frets are a little worn but have years left in them and the electronics are all intact and working.
Ok, I fully accept its a bit of a gamble and a fixer-upper. But I have been waiting years for a black Spoiler to come up and its (relatively) cheap. Most Spoilers in Europe are natural finish and typically around the $2500 mark.
