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.
Identify this lens! Mystery.

Hmmm...Rotar?
Never heard of it but maybe a little research will dig up something. Will look into it.

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.
