I bought an screw to M adapter and my 1932 Nickel Elmar works fine on the Monochrom M. It will even safely collapse and doesn't go in quite so far as the Elmar M 50 2.8. It certainly sits flatter than that lens on the front of the camera, however.
The only concession mating the various parts is that the bell push infinity lock cannot be released once the adapter is fully on. I take the lens off infinity and then screw the adapater home. The combination then mounts on the camera without any interference by the lens release button. Apart from not having an infinity distance option, not necessary with the fastest aperture f3.5, there is no limitation at all.
Removing the adapter from the lens is easy with a spare rear lens cap.
