Have a Fender P bass with a 369XXX neck plate and a neck that measures 1.58 at the nut. This is supposed to be a '73, but I'm not sure by the codes. The serial # could be in the '72 range maybe? Anyhow, all electronics are changed, so no help there. It does have screw holes for the "thumb rest" in both positions under the non-original pick guard. Anyone recognize this neck stamp (0103 1953) or body stamp???
