Why do Oehler system clarinets often have a plateau key for R2? I don't see the advantage over a ring. A plateau for R3 and/or R1, to reduce the stretch, I could understand.

On mine, there is no key under the plate, the hole is on the side, much like a bass clarinet R3.

Ah! Thanks. That makes sense. Maybe I should actually get one in my hands before asking silly questions.

The tonehole for RH2 has been moved to the side to put it in a better acoustical position, so the RH2 fingerplate (Griffplatte or Oehler-Mechanik) operates both the small side key covering the Bb/F tonehole as well as the forked Bb/F vent key (further down the lower joint) together.

Sometimes you see an intermediate solution, where the middle hole is still present, and only one of the two side vents exists: see the attached photo of two Uebel clarinets. This is the only difference in mechanism between them. I'm not certain if these are both considered variants of Oehler system, or whether that terms applies to the double-vent case. Presumably the double vent is acoustically better, as you can get a larger hole in the right location.
But I have to agree with Dibbs: in either case, you have a big stretch. The big advantage of the Boehm mechanism is that the RH rings are closer together and the hand position (for people without monster hands) is much more natural.

While there's no tonehole directly under the RH2 fingerplate on Oehlers, there's often a circular recess cut into the joint immediately below it so it doesn't make contact with the joint surface.

The uppermost is a 6 ring "German system" as still used in student-grade clarinets (photo: a new Yamaha 457/20, btw. a fine instrument for its price, known for good intonation).
The other is indeed an Oehler model, characterized by the two side keys ("Resonanzklappen") actuated by the "Griffplatte". On my photo from yesterday you can see the closed recess under the Griffplatte mentioned by Chris.
"Voll-Oehler" an Oehler system is called with an additional key on the bell for E- improvement, actuated by the right thumb, and on top models an additional mechanism for deep F- improvement. The Oehler successors, e.g. Arthur Uebel, established this (at least the bell key) as standard. Oskar Oehler himself, as far as I know, didn't use these improvements.
I find John Peacock's Oehler- Uebel not quite typical for F.Arthur Uebel's style. Could that be an earlier model by F.G.Uebel (F.Arthur's father) from Gopplasgrün or Wohlhausen? How is it marked?

MichaelW:
My fingerplate Oehler is marked "F. Arthur Uebel Markneukirchen" . But it's from the DDR days, made in 1976. All the key shapes are different in the modern Uebels.
