Aynone to identify my weird Fernobjektiv 500/8 mount? :)

Oh sure it fits the Ouroboros camera. Just kidding. I have no idea.

Do you have two sections? Is it possible this was the front end of a two section lens?

The clip around the mount looks very much like a E Clip used in engineering to locate something like a bearing on a shaft or a brake cylinder onto the backplate - as in this picture.

So my guess is this has been modified at sometime, and maybe the clip holds the lens in place when it it is mounted on a plate mount? But, the E clip should have a groove to fit in.

Is this how the lens should look?

Hi, is it the "Fernobjektiv" from Zeiss?
It was build with M42 mount and with EXA mount.

I have a catalougue where they wrote that the Fernobjektiv may have for example Praktina, Praktica (M42), Contax und Exa/Exakta mount.

It is not M42, of course.
It looks similar to EXA but I miss the third "nose" at the ring.
I do not know the Practina mount.

It is Exakta mount, but using the external bayonet claws to make more clear space at the mount throat; some long-focus lenses use the external bayonet.
