Bill, I think you should ask for advice on whether or not you should adjust the truss rods if you're going to have the strings (and the tension they provide) absent for a while.
I'm no expert, but it may be the case that, if you're not going to have strings (and the resulting tension) on the bass for a while, you MIGHT (or might not) want to adjust the truss rods to prevent damage/issues.
You might want to ask members about this/members seeing this might want to comment.
While I tend to prefer the look of natural wood, fcspoiler//Flips suggestion of a color finish seems compelling -as it would eliminate concerns over cosmetic blemishes; properly done, the mutilation done to this bass by the previous owner(s) would not be noticable. Of course, only you can say what you would like/prefer.
I also want to echo dannobassos thoughts... if/since you may require replacement electronics, it may behoove you to consider Distilate and/or Europa/Rogue electronics.
Briefly (in case you don't know), Distalite electronics are the same as Spoiler (volume, filter, [2-position] Q switch, [4-position] pickup selector PLUS a pair of 3-position bass & treble boost/flat/cut toggle switches (which can boost or cut each frequency 6 dbs).
Europa/Rogue electronics are the same... except the 4-position rotary pickup selector is replaced by a pan/balance/blend control.
And again, the Elan package is like the Spoiler electronics -except that it DOESN'T have the bass & treble boost/flat/cut toggle switches... so it has a balance/blend/pan control INSTEAD of the 4-position rotary switch.
For specific price info, you can use the price quote generator -on the custom quote generator and/or call Alembic for specifics.
The Spoiler and Distalite models are no longer standard offerings, so the price quote generator will likely not offer info on these options. But have no fear, you can certainly get replacement electronics.
In case you don't know, much of these issues are ususally taken care of by Mica -daughter of founders/owners Susan & Ron- who recently had a baby, and has been taking time off accordingly for several weeks.
As a result, such requests/inquiries are likely to be a bit more delayed than would generally be the case... be advised.
Again, best of luck with your salvage efforts. It doesn't look to bad, and with some effort and fortitude, you'll have an awesome bass. And this forum is a great resource, full of people who are generally inclined to share their experiences with you.
Take care.
