just got one...

But I don't know anything about it. The VM doesn't mention a lot (just "several"), and the one description is dated much later than this one must be, as the Jamin name is written on it.

Original case - "secret" compartment in the lid where the original flange and a front plate was hiding..

beautiful condition.
Compleate as I can tell.

on the lens is written "B" and "PORTRAIT" - on the base of the barrel it says "A".

I am almost sure the Portrait "mode" is a petzval...

6 extra lenses to combine - 8 waterhouse stops.

Anybody know about this kind of set?
