Blimey Luke, talk about apples & pears!
That Andy Baxter bass is a genuine, all-original Precision from one of the UK's best-known and most reputable dealers. It is also IMHO horribly over-priced, and it will only be worth that amount of money if someone buys it for £13,500. Which patently has not happened. Yet. 😉
The bass in the OP for this topic may very well be built on a genuine 1958 but there is no way of knowing. With no provenance, no evidence, but plenty of admissions about refins and parts replacements, it could be just about anything.
