Ah man, I would love a cool old carved bass like that to restore. I agree - you should take the bass for an evaluation - throw the luthier some cash for his advice on proceeding and explain to him that you are serious about doing it right.
A cool luthier would be fine with helping you out, IMO - if he tosses you out for asking for info (even if you are willing to pay him for his advice) - then I'd find another luthier.
These guys are master craftsman, IMO, and their time is worth money. If you go in there humble, and explain your ambition albiet lack of funds, I'd say you have a good chance of taking some good notes. Depends on the guy and your personality and shmoozing skills, of course.
