Bass Neck Unfinished - Possibly from a Famous Workshop?

This item was obtained at auction some time ago.
I kept it with the intention of using it for a custom-built bass someday,
but I don't have much free time, and rather than letting it sit unused, I've decided to list it for sale.

According to the description when I acquired it,
it was apparently made by a workshop commissioned by a famous bass manufacturer.
It seems that in such cases, they sometimes produce multiple units as spares or with different specifications.

Since they couldn't sell unfinished items under their brand or workshop name... they seem to have ended up on auction.

In my personal opinion, the quality of the wood and the feel when holding it are comparable to a 200,000 yen class bass from a certain workshop-style manufacturer I used to own.

For this reason, as this is an unfinished item,
I cannot provide further details here.
Please only purchase if you understand from the photos.
