Congratulations on [yet another] sweet bass Craig.
Interesting; the model SSSB-4 suggests this is a short-scale Spoiler. Maybe an additional custom spec to the Crown headstock?
* I see the seller on Reverb also had what looks to be a SC Signature, presumably also a short-scale... makes sense.

** Super-glue and ebony dust by the way... that's the ticket. Easy, invisible fix. I would humidify it for a couple weeks first, to swell the wood as much as possible naturally.
