Found this old tiny lens in a 2nd hand store for 1€. But what is it? From what I can find it's an old french lens company but that's it. What is the lens mount (the lens mount is 2.7~ cm diameter, screw mount is 0.4 cm deep)? Any way to mount this on a modern camera?
What camera was it used on?

Enlarger lens?

Ok so they also made m39. This is way smaller, never seen this small a mount before.

Sorry I did some wrong measurements of the lens mount, look at inches instead of cm, sorry for wasting your time Sad. The lens mount is 2.7~ cm diameter, screw mount is 0.4~ cm deep.

Anybody know that lens mount?
