Help needed with ISCO/Schneider projection lens serial numbers

[simple-joy]

Together with a friend of mine, I'm trying to create a proper overview of ISCO projection lens serial numbers (+ later on likely also the Schneider equivalent). We've done a lot of work already but could really use the help of everyone here to fill in the gaps and answer the remaining open questions.

If you have some ISCO or Schneider cine projection lenses (or even "Made in Germany" Kollmorgen ones), it would be great if you could share some of the data here

The full inscription incl. serial number would be the main thing of course, but if you can share some more detail about coating, diameter or optical design... everything specific helps as well.

And because there are many different shades, particularly in the golden series, an image or comparison between the look of several lenses is highly appreciated as well, if it's not too much of a hassle to produce.

Here are some of the main series we're looking for:

Optische Werke Göttingen, JSCO Kiptar
ISCO Projar (only cine slide projection with 62.5 mm diameter)
ISCO Kiptar
ISCO Super-Kiptar (also Philips SK)
ISCO Kiptron
ISCO T-Kiptagon (also Philips EF BF)
ISCO Cinelux-Ultra
ISCO Cinelux-Xenon
ISCO Ultra MC
ISCO Ultra-Star HD
ISCO Ultra-Star HD Plus

Schneider Kreuznach Projektar
Schneider Kreuznach Cinelux Ultra
Schneider Kreuznach Cine-Xenon
Schneider Kreuznach Super-Cinelux
Schneider Kreuznach Cinelux-Premiere

Kollmorgen Cinelux (made in Germany)

Thanks a lot in advance!
