Hi,
have you tried looking at the “Deko“ stuff from Thomann?
Here‘s one example
https://m.thomann.de/gb/harley_benton_custom_line_clr_resoba_deko.htm
This isn‘t specifically what you‘re after but new stuff, including J and P basses, does come along quite often. They‘re supposedly damaged and not playable but numerous reports on BC say that this is often not the case. Inexpensive and possibly ideal for project stuff.
It pays to check regularly.
