A Roeschlein-Kreuznach-E-Telenar, 135 mm f5.6 lens from Ebay, one I have been after for some years, it is 39mm screw mounting, but not Leica, it is for the Braun Paxette, and is the rangefinder coupled version.
Braun supplied leness for the Paxette from 35mm to 135mm, 45, 50, 90mm., etc., from various makers, with Enna and Roeschlein both doing the 135mm F 3.5, but only Roeschlein supplying the F5.5 baby telephoto version.
Very small indeed for a 135mm lens, it goes with the small form of Paxette camera. All the longer focal length Paxette fit lenses are scarce these days. The small aperture can be compensated for with 200ASA film.....
I can fit a Leica adaptor for M 4/3 with a short M39 extension tube, which have to be home made. I have seen M4/3 adaptors for Braun, but they are very expensive.

Cute! I have a Braun adapter, well made but totally obscures the rangefinder window on the Leica. Yes I know I should use a viewfinder, but the rangefinder window has a great approximation to the FOV of a 135.
The 135mm Paxette lens arrived, and is in better condition than the Ebay pictures suggest, smooth satin chrome finish, no marks or dings. I have tried it on the Olympus M4/3, but it needs a proper adaptor made from a Leica M4/3 mount, plus a 14mm extension in the form of a tube, to get the lens to film register right.
Some of the Leica converters have the thread on a separate satin chromed ring, secured by grub screws. Once released, the threaded ring can be mounted on a short tube that is made in a lathe, to fit the the back half, with the M39 threaded part used as the front, saving machining the thread.
Despite being F5.6, the image is bright and clear for focusing etc., as good as the standard Zuiko zoom lens. Equivalent to a 270mm F5.6 on M3/4 format.
The 135mm lenses from Roeschlein had a reputation for edge fringe effects, but the micro format only uses the centre so no issue. It does show a bit on film at full frame, but only in colour, looking a bit like the digital purple fringe problem.
