Looking very strange so I thought to mention it here.

That thing looks like it's spent some time in the bottom of a rowboat!!! I don't recall seeing round position markers on any other instruments... or pickup rings.  That's a 3 pin XLR rather than a 5 pin.  Hmmmmmm......

It does look strange...no oval inlays, different knobs, teeny horns...

If it was a '79 Series instrument, wouldn't you expect an exposed dummy coil?

This one has been posted at the Club before.
 
Here's the original thread about the bass (archived). On the non-archived part of the thread there's a response from Mica, but no actual confirmation whether it is an Alembic.
 
December 2003 thread showing some modifications by owner navybass, plus a posting in 2006 apparently by a new owner.
 
February 2004 thread showing navybass's inlay work on the peghead.

Could be an employee bass? I am a bit puzzled but it is rather interesting.

I went through the old threads: it's not altogether clear that this is really an Alembic.  But assuming that it is, it would have started out as a SI.  But to call it a Series instrument now is deceptive at best.

The seller sent me some pics.  This bass has had a  really rough life!!
