I've been in touch with the seller, and he sent me a bunch of additional pictures. It seems to be legit. His description of how the hole from the original pick-up switch selector is covered is interesting. He said it looks like an inlay of the Alembic logo, which would imply to me perhaps the factory made the change at some point in the past.
He hadn't sold it as of yesterday, but said he had someone coming up from Austin to make him an offer.
Joey, I think you are spot on - I just don't have the time to fool with it, but would love to see a club member get it.
Just curious - did the graphite necks have a truss rod in them?
