I bought a broken Braun Super Paxette II BL camera, but the purpose of the purchase was the four lenses that came with the camera. The first one is the Staeble-Telexon 135/3.8. The second is the Staeble-Lineogon 35/3.5. The third is the Steinheil München Quinon 1:2 f=50mm.
This is a lens from the late 1950s. There is an advertisement from 1957 February:
There were two M39x1 versions of the Quinon 50/2. The first was for the Leica M39x1/28.8:
This is a lens of the Sonnar (Sonnare) family: 7 elements in 3 groups. This lens is quite expensive today.
My Quinon 50/2 is a different version, it is actually M39x1/44 (for a Paxette camera). It has 6 elements in 4 groups.
It is an evolution of a Double Gauss: an asymmetric Planar (also known as Biotar or Xenon).
(similar optical design)
This Planar (Paxette) version is much cheaper than the Sonnar (Leica) version.
The rear part is protruding:
I think it is because of the 50 (52) mm focal length instead of the more common 58mm of SLR Biotar lenses.
The aperture has 12 blades:
The aperture ring has click stops at f/2, f/2.8, f/4, f/5,6, f/8, f/11, f/16.
The filter thread is 40.5mm. The front part of the lens (with the filter thread) rotates during focusing. The minimum focusing distance is about 1m. The front (threaded) part doesn't rotate when the aperture is changed.
So now I have 35mm, 50mm, 85mm, and 135mm lenses for a Paxette camera. The only pity is that it is impossible to use this Quinon 50/2 with a Pentax K-mount SLR (and I mean a film SLR first).
