Hi Aurel
Yes, but f3x.com sells the original Caldera (as it was also used in F3B at the World championships in Kirchheim I think).
Apparently there is a newer variant called Caldera R, so it is the third generation (first Caldera, 2m Caldera S, now Caldera R).
I hope Dieter can add some words to the Caldera history and the latest version.
Best, Reto
