A request to my German (speaking) readers

At Friedrichshafen fair last June 2022 I bought some stuff from the seller at table A012 (https://youtu.be/BH29tY4Sjyc?t=154 and next 30"). I would like to get in touch with him to ask if the has more (not complain about something broken! HI).

Is there a German forum where I could ask if someone knows him? If you asked me for the Italian scene, I would answer "ARI Fidenza forum".

Please let me know with a comment or via email to ik1zyw@yahoo.com .

Thanks!
