Stephan says thank you, it appears he has type D. Still funny, he seems to have a different timer, the increments are different. Probably a replacement.
The timer is working but it looks like it needs a good cleaning, he will do that soon.
After the restoration is finished this Keymatic will go to a collector in Stuttgart. He has a Keymatic 3224 now that is in a bad state. Stephan wants to restore that one too. I will start a new thread about that soon.
