I don't think a signature series neck would have an American Special serial number. Nor an American Special a bullet truss.
The headstock shape is wrong with the lower curve not pronounced enough while the curve from neck to the top is too long. The decal is not correct either in that the 'with synchronised tremolo' part is too big in comparison to the 'Stratocaster' part a little like it is on the Japanese ST68s. It should start just after the beginning of the 'E' of Fender and finish before the end of the first 'A' of Stratocaster with the pat nos underneath on the originals and Custom Shops.
The 12th dot spacing looks wrong too for a CBS era headstock model but that could conceivably be the angle of the photo.
