I just saw this on ebay UK and wonder if it is a genuine alembic article?
I'm sure I read on the forum here that Alembic don't sell their logo's So I was very surprised to see it.
maybe Mica or Val may wanna check it out.  
 
It's  not even a good enough picture to make you wanna bid on it anyway.
 
 
Maybe someone has taken the Alembic Logo off an instrument and gold plated it or something like that.

Yep alembic did at one time sell the logo but they stopped because the logos were finding their way on non-alembic instruments.
