Together with a friend of mine, I'm trying to assemble an overview of ISCO projection lens serial numbers. I already managed to provide something like that for the early Optische Werke Goettingen, Kiptar, Super-Kiptar era:
However we don't have a firm grasp on the later (golden and red) lens series yet, where ISCO seems to have reset the system frequently.
Here‘s my current theory:
- I think ISCO restarted their serial numbers after the 101XXXXX numbers the golden Super-Kiptars/Cinelux-Xenons and some early Cinelux-Ultra MCs shared.
- some of the later Cinelux-Ultra MCs got a five-digit number.
- the Ultra-MC (non Cinelux) might have gotten their own numbers as well. they started with 5 digits and were later extended to 6 digits.
- The Ultra-Star HD already started with 6 digits, however with 0s in front.
- the Ultra-Star HD Plus also got their own system.
If you have any of those lenses, ISCO Cinelux-Xenon, Ultra-MC, Cinelux-Ultra, Cinelux Outdoor, Ultra-Star HD, Ultra-Star HD Plus, Kiptron and can provide some serial numbers it would help us out a lot.
Thank you very much!
