Enteries in the Formel Vau support race at the 1970 German GP at Hockenheim included:
Knut-Holger Lehmann driving an 'Austro Kaimann, as were Gunther Rosch,
Joachim Schlicksupp, Ingo Schneider, Norbert Wieland and Rainer Zefferer.
Not being that au fait with the Formula Vee cars I just take the programme entries at face value.
