All is in the title. This version looks quite uncommon, but I cannot identify the mount. A seller of similar lens has identified it as arriflex, but it is not. Any idea?

No idea but I think you may be able to swap the mount easily by removing the screws.

I think a T2 mount lens with adapter. Grasp the knurled part of the adapter and unscrew it from the lens body.

That is a very unusual bayonet! If you DO work out what it's from please post it on here!

Indeed! … and if this is the case there's a good chance there's at least an abbreviation of the mount designation on the "hidden" face of the adaptor.

Strangely, the knurled part does not come off, and there isn't any screw in the little holes. I believe the knurled part was intended to help to mount the lens on the camera. Do you know if MOG (or other east german brand) participated to any soviet space program? This lens was found in a soviet optical institut (back then they collected a lot of german lenses, sometime quite rare). Since I cannot find the camera it was intended for, I try to find in niche "market" like space camera or technical devices.

Might be a long shot but this somehow reminds of: https://www.aliexpress.com/item/32828268644.html

this lens was only made in m39 fitting. Many of the early batches were made for military including Sweden.

Is quite possible that it may have had a bespoke adapter fitted to it. What's the back focus distance ?

Judging from the looks and robustness of the mount I would hazard a guess this is a breech-lock mount, not a bayonet mount.

Possibly a bespoke industrial or military mount system. The slot in one of the tabs likely aligns with a pinned protrusion in the breech lock on the "camera" to fix the correct orientation.

Not too dissimilar from the system used on the Pentacon-6 mount, only that one is much larger and the orientation pin is on the lens and the slot in the camera.

On the off-chance that this is a bespoke limited production version, did you try if the knurled part unscrews clockwise rather than counter-clockwise?
