1. It has a register key that alternates to a dedicated Bb vent - just like alto clarinets and simpler bass cl.

2. It has a double-pad for low C. The presence of a lower one adds more venting for C# so a closed hole isn't reducing the venting. I've seen this on old Malerne basses (like mine) and some other old bass pictures.

On altos and basses, the register / Bb system is necessary (I deduce) because they use a bore that is disproportionately smaller than that of a Bb cl. They can't get the register vent to also tune the Bb.

I assume the double-pad system is also solving a reduced-bore problem.

So I think the only reason this cl. would have been built this way is that it was made with a very reduced bore. Knowing the length of the cl. would be a clue to further conjecture.

Hm, that register vent kinda gives me a bit of Stubbins mechanism vibes. Neato!

Yeah, it's very odd for even a Full Boehm soprano.  That is some rather complex linkage, and a lot of design work involved.   I'll bet that is a valuable horn.  Hopefully, the bridge key survives.  Player or not, you can tell a lot about someone from their inability to line up the bridge keys correctly.
