Just spotted this on Reverb UK and it's in London.

This supposed to be my first Alembic, but the owner didn't want to sell it then, now after 3 years he contacted me a told me that he finally decided to sell it, but I have my Series 1 now.
He's a nice person, talk to him quite a lot about that bass. Looks beautiful.
