According to Schneider there are two thread mounts for this lens: one 25mm and the other 39mm (Leica screw mount). I use a 39mm to 42mm adapter to put a Rodenstock Rodagon 105mm f/5.6 on a bellows, and that adapter was easy to find. I don't know about the 25mm version. Of course, the lens itself has no focus control, so you'll need a bellows or something; otherwise you have to mount it at a fixed distance from the film/sensor plane and only get one subject distance in focus.
Novoflex make a bellows and sunken mount for the Schneider 80mm f/4 which allows infinity focus - and it has tilt and shift movements too, I think. The Novoflex website is a bit rubbish, but it is available from www.speedgraphic.co.uk.
