Hello,
Well, I'm having a bit of bad luck. Either Erich Mansfeld doesn't appear in any of the photos I have, or I don't have the history (yet). The same goes for Fritz Jungé and the two Kühls, Ferdinand and Otto....
On the other hand, I did find Kay Meyn's photo in the history of RIR 230, so that's one for me 😉
It's only a postponement...
Thanks again for your precious help.
Sincerely
Joel
