There are no team mention in race program, just cars and drivers.
Pedrazzi was at the race, as also members of autoclubs from Poland, Germany, Austria and so on. But no mention of Gianferrari in czech newspapers. Just Ferrucio Testi as a leader of the team and Augusto Caniato as a third driver (but never started).
But two years later, after 1932 race, Scuderia Ferrari send a letter to Lidove Noviny, where they explain another loss at Brno and there was also said, that after they send cars to Brno in 1930, 1931 and 1932, they will be back next year and fight for the win again.
