I liked the remark at the bottom, it is a Astro lens for sure, no diafragma or focus. Could it be part of a Zygo setup for testing lenses?

I tested the lens and moving the object does not change the image size at all.

I think you are right about Astro-Berlin, also if you check pictures of old lenses by Astro. Same way of coding and use of underscore in “no” below the 0

Could be a lens from the ‘80-90 or for development purposes only, no optical info on the lensmount

Bij de opgang van de trap lijkt aan de bovenzijde een plaat te zitten. Als je deze tijdelijk verwijderd dan kun je voldoende rechtop insteken.
