I don't have any emails from the address you have posted here, but I'm always glad to help. This bass would have had the serial number stamped in the Ebony fingerboard below the 24th fret. It looks to me that it was purposefully removed during the extensive modifications this bass underwent. I'm afraid we'll be unlikely to identify this bass.
It's probably started out as a 32" medium scale Spoiler with a 3-piece Maple neck, Ebony fingerboard, and solid Koa body. I'm concerned the electronics are not original as we don't offer any concentric controls, and the control pattern is not typical - and ALL Spoiler basses from this time had the same specifications. Can we see under the hood?
I saw this bass on the Club before. Wasn't it on ebay recently? I'll dig around here and see if we came to any conclusions about it.
