In late September of last year, Alembic Stanley Clarke 5-string SN #96SJ9986 was sold by a private seller to Sun Ridge Guitars, who then subsequently sold it to an undisclosed party.  This is the original listing:

I'd be extremely interested in making contact with the current owner and finding out whether this particular instrument might be available for sale.  Alternatively, I'd appreciate hearing from anyone who might have any other Alembic short scale (30") 5-string for sale.
