RE: Graupner Caravel
Not really, but try this: Go to the [link=http://www.75-jahre-graupner.de/]75th anniversary website[/link] and just wait till you're redirected to a new window with "running" catalog pictures. Click on one of them to get a new display with a vertical timeline on the left. Move the actual year marker to 1961 (with the mouse). In the slide show starting in the bottom right corner of the window, it's the 7th picture I think, you will recognise it even though it's tiny.
The text reads (my translation):
"The winning American 1960 R/C-model world championship team chose their route home from Zürich via Kirchheim/Teck to visit the Graupner factory and catch up on the latest regarding the German model building products. (From left to right: Dr. Walt Good, A.M.A. president; Bob Dunham, multi-year American R/C-model champion; Edward Kazmirski, winner of the 1960 world championship in Zürich.)"
Other pictures there show the then actual Bellaphon transmitters, but the one Ed is holding looks boxy and not rounded, so I think it's a prototype Variophon. All a bit strange since it came out only 1962 (and pictures are shown for that year) and the WC was 1960, but they arranged the picture in between.
Added a screenshot. They seem to wear the same shirts as on a picture shot in Bern ([link=http://www.modelflight.regheath.com/mf137/airspaceset.htm]here[/link], scroll down). Maybe the Graupner people selecting the pictures for the anniversary website didn't know much about that picture and the caption is just nonsense. Maybe Graupner had their products in Bern to boost them.
Edit: have to correct me, must be a Bellaphon because the antenna is on its left side (Variophon had antenna centered).
