[quote name='thedonutman' post='799141' date='Apr 7 2010, 07:53 PM']The inlay was done by Sims - it's actually in their gallery. Admittedly it's not a great quality inlay. You can't see it in the pictures but there is a lot of filler and the MOP itself wasn't cut perfectly.[/quote]
Don't want to sound harsh but the fact your reading that much into it seems like perhaps your just entirely unhappy with it. It seems your now finding fault with everything on the bass. Im really not criticising, its a natural reaction when your dissapointed with something.
Personally I am not 100% the nut needs changing, in fact the JAN original is quite desirable now days and still offered as a custom option on new Warwicks.
I think it just needs adjusting back into place.
Fret's probably need a change rather than a crown but thats just my opinion, as for the refinish hmm I never know with a solid finish like that, I can understand why you would want natural oil but its a big job and you never know whats underneath!
EDIT - Also serial number?
