Thanks for getting this thread going Zaphod!
Mine's a red "Ultima Superleicht", mostly likely built in '75 or so.

The problem with mine is that it doesn't have a serial number ... if it did have a number it could possibly be 00000001. I'm still working on getting that confirmed and waiting for the weather to clear so I can get some nice photographs.
