If I was after an older P-Bass, I would probably go for something like this (As long as the Truss rod is okay).
After purchase I would just sort out the pups and try and source an aged or repro/relic scratch plate like in this link.

But I'm not after an older P-Bass. So good luck, I'm sure there is a few quid to be made, either way
