I seem to recall a little while back, someone was wondering how many total Distillates were produced, and the answer was the different models weren't tracked.
I think it's kinda' cool how they build these beautiful things, each one a unique individual with its own identity, to a degree that ideally, they never need to see them again, then send them along. Sometimes they show up again, many years later, which is pretty amazing in itself when you think about how big the world is and how relatively few Alembics there are.
As the total approaches 15000 (might already be there?) it can't be an easy job to sort out which numbers were what, but I would like to add to what FC started, or contribute to a comprehensive list in some way.
