Zeiss lenses: Sphaerogon and Perimetar

Hi there,

are there any other Sphaerogon and Perimetar lenses known in the world, apart
from the two lenses that showed up again lately, after having disappeared from
the famous "Zeiss lens collection"?

thanks for any hint!

 

operation paperclip?

I guess that in any case they must be exceedlingly rare.
