If I remember it right, the thread on the front bit of a screw Leitz 90mm isn't L39, and is intended to attach the thing to a Visoflex or similar. One caveat on mixing Leitz and other L39 gear: there is no problem with Canon equipment, but there is with Russian stuff (Fed and Zorki). These have different mappings of focal distance to cam travel, and will badly confuse a rangefinder. Pity, because some of those lenses are very good value. Another one: there seems to be no standard at all for flange-to-focal-plane distance on enlarger lenses. I have two Schneider Componon lenses (35mm and 100mm) - neither is remotely close to the Leica camera standard.
