Well, guys, that's it for my TMs.
I am missing the following makers (and hope that some of you could post their marks here):
Chromolit
Arthur Evertz (AES)
Gebr Heller, Schmalkalden (the anchor)
Christianswerk
Aug Mertens
Undine (Kuno Ritter)
I have also heard that the following may exist, or may simply be the creation of our ingenious friends from what used to be behind the Iron Curtain:
I S Wolfertz
Klitterman & Moog
Aesculap
I also know that there are many variations to the marks posted in this thread. I would love to see them all.
This was fun.
John
