This old lens was sold for Braun Paxette cameras as an early standard lens. This is the second set of photos with a different adapter that fits better. Wide open it's a bit soft. Stopped down it's fine. At F16 you can see what it is capable of. It's astonishing, how short and light it is, even if you add the adapters. A nice very small lens.

The M39 Paxette Mount is the same thread as ordinary M39 (Leica), but  a different flange focal distance.
