The Staeble-Telexon -E- 1:5,6/85 is a telephoto lens for Braun [Super] Paxette II rangefinder cameras, characterized by the M39x1 mount with an unusually large flange focal length of 44mm.
Made by Staeble-Werk, [West] Germany.
The letter -E- in the name indicates support for coupled rangefinder (which is on Super Paxette II cameras as opposed to just Paxette II).
Perhaps the "E" comes from the German word "Entfernungsmesser" (rangefinder).

I don't know the year of the lens, probably 1956-1958 (or later).
When focusing, the whole front part (together with the aperture ring) rotates. For a rangefinder (not SLR) camera this is ok.
The scale is in feet and meters, the minimum focusing distance is slightly less than 1.5m.
The aperture ring with clicks (it surprised me) in the positions: f/5.6 - f/8 - f/11 - f/16 - f/22 - f/32.
The aperture has 10 blades:
This is not a particularly rare lens, it can be found in catalogs and manuals of the time:
(it cost 75 DM in the 1950s)
However, there is no optical design information, only a claim that there are 4 elements (Linsen) in the lens.
By chance, I found such a "Telexon" mention in the magazine "Реферативный журнал"/"Referativnyĭ zhurnal" (1961):
So the Telexon 135/3.8 is a 4-element lens with a cemented front group. If the name (Telexon) refers to the optical design, then the Telexon 85/5.6 must have a similar design. Most likely something like the Wrayflex Lustrar 90/4:

Of course, the f/5.6 of this Telexon is quite slow. But for what it is, this lens is tiny for 85mm.

By the way, my copy of the Telexon looked good, but the focus ring was too stiff. I took it apart and cleaned it, there was very old grease in the threads on the back for the rangefinder. The lens is easy to disassemble, but must be reassembled correctly (to preserve the thread positions). It's a pleasure to use the lens now.
