I wonder what the catalogue-price was, when new

Can't help with the 7 place nosepiece but have a 1959 US price list for Zeiss Pol microscopes (WL and GFL) that gives the price for the 5 place nosepiece.
Worth around $200 in today's money

Thanks for the price-list snapshot
Relative values are clearly not an exact science:

There is as you say quite a price range ...

I did not know that there was an Olympus BX version:

Re: Zeiss 7 place nosepiece
Looks just like this one which states it is for the Universal and Photomicroscope: https://www.ebay.com/itm/ZEISS-Objectiv ... SwoQddlldzmicrob wrote: ↑Wed Aug 26, 2020 7:19 amWhich microscope is it for?

Re: Zeiss 7 place nosepiece
There is mention of it in this thread , viewtopic.php?t=6184#:~:text=The%20Zeis ... e%20length.
I'm still little confused about the use of the telan lens in the Zeiss photomicroscope and Universal nosepiece. If it is used to convert the ray bundle to infinity, so that accessories can be installed without compromising the tube length, then there must be a further telan lens downstream somewhere in order to convert the infinity bundle back to convergent. Do those microscopes have such an arrangement?
The other two microscopes I know of that have a "telan" lens in such a location are the AO series 4 and the B & L Flat Field Dynoptic/Balplan series, which utilize that location for a supplemental lens in different ways.
In the former, the lens appears to be primarily a correcting optic: correcting for field curvature, lateral ca and for a tube length differential between the objectives and the stand itself( 160mm to roughly 200mm). There is no requirement for a further lens downstream because the ray bundle stays convergent. It is called a compensating optic, if I recall correctly.
In the case of the B & L system, the nosepiece lens ( called a negative corrector lens in the patent) , magnifies the image and converts the bundle to an infinite bundle for the duration of it's path to the viewing head , where it is then redirected to a convergent bundle in an additional telan lens.
