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 for your help!

Would appreciate your help with ISCO/Schneider projection lens serial numbers
