Agree I don't think the paint or the pickguard is original, and that would make me question the rest of the bass too. I would want to see pictures with the PG and neck off so I could verify the dates on everything. If you look at the picture of the tuners and bridge you can see that they are old and aged. IMO the paint, PG, and PU covers look too good compared to the hardware.
