Identify this lens! Mystery.

Made in Japan. Very tiny 135mm (serial number not visible, no other information on front). The entire front half with element turns, instead of moving back and forth with a turning focus ring.

Exakta mount lens by the looks of it.

Looks like an Exakta mount lens with a manual or preset aperture ring.

It just doesn't look like it could cover a 35mm film plane... Maybe I'm wrong. Notice that the overall diameter is nearly half of a regular exakta lens.

I recall my own Exakta-mount Tessar to be very small. A simple check would be to measure the diameter of the mating side; the Exakta-mount is about 38mm across.

There is nothing to accurately reference the diameter of the lens in the photos that you supplied, a hand does not count as hands come in all sizes.

Non auto Lenses for Exakta are not very big and there is a myriad of them by various lens makers, made throughout several decades too.

Almost any lens making firm worth its salt made lenses to fit the 35mm Exakta camera.
