Help Identify Vintage Custom or Parts Bass

Picked this bass up today in the SF North Bay Area. Very interesting bass with high quality parts from 70’s. Had a fretless neck mounted that looks to be custom made by a skilled luthier.

Birdseye maple neck with truss rod adjustment at headstock. Any older bassists out there recognize this work?

Mid to late '70's for sure. Hardly and wear on those vintage pups.

Mucho mojo!

Should have mentioned that the body is 1 piece ash. Weren’t there very few companies making aftermarket bodies in the mid to late 70’s?
