Much debate surrounds that. The debate you refer to is Seymour Duncans version of events surrounding supposedly two Strats, both with #0001 serials, that Seymour owned in the seventies before selling one to Phil Taylor, who then supposedly passed it on to Gilmour in the mid 70's. FWIW, Seymour is the only one making this claim, and on his own forum. Seymour claims that guitar is pieced together of a 57 neck, a different 57 body and 60 pick ups. That's fine, but Gilmours neck and body are both 54's, and the anodized pickguard and gold hardware are unusual and suggest a special build like a #0001 of a brand new design would be. It's likely that Seymour Duncan was thinking of guitar different from this 1954 Fender Stratocaster #0001 that David Gilmour currently owns. The neck and body are both dated and signed '54. The pick ups appear to also be 54's according to those who have seen it. All evidence suggests that it is a 1954 Strat with serial #0001. The historical significance of this guitar is incredible. The fact that it's owned and played by one of the greatest guitarists is just beautiful.
