Some europeans also seems to have started their connection with Iwama style aikido on the american west coast (Witt, Klickstein etc) and then brought it back to Europe (Wolfgang Baumgartner, Roland Spitzbarth).
According to the website of the Meerendonks, a teacher called Volker Stanzel had a connection to Saito in as far back as atleast 77.

Also, Göteborgs Aikidoklubb claims to be the oldest Iwama style dojo outside of Japan.
