Thank you for the suggestion. It does not seem to be a LTM lens. It may 
be an old M version (diaphragm only to 16). It does not have a screw 
mount. It has a bayonet mount, and it mounts just fine on a Visoflex 
II. The bayonet mount would of course fit on the M camera, except for 
the fact that is is recessed into the lens. I wonder if it is the 
optical group of the Summicron on a short focusing tube type ZOOEP.
I have uploaded 3 pictures,

if someone knows what I need to mount this lens on my M3, please let me 
know.
Thanks again.

Juan
