Thanks for your comments Aero71. Obviously I'm not deliberately trying to commit fraud here so here's what I know about the body.
Bought here on basschat as a complete bass a couple of months ago, the USA neck and serial number consistent with 1999 (not 1990 as originally advertised):
Some discussion and opinions from basschat experts on its authenticity:
And regarding the pick guard, there is no cutout because in the American Traditional neck the truss rod nut is in the headstock.
I believe American Traditionals were not strung through body.
So, plenty of evidence for this being a US body and none I am aware of supporting it being MIM.
