Giuseppe Baldoni and A.L.F.A. at 1919 Parma-Berceto.  Date may be 5 October 1919, based on various sources that have covered this race, where Enzo Ferrari had his debut.<a rel="nofollow" class="external autonumber" href="http://www.modelfoxbrianza.it/EnzoFerrari_Corse.htm">[1]</a> Vintage racing historian Leif Snellman also uses this date.<a rel="nofollow" class="external autonumber" href="http://www.kolumbus.fi/leif.snellman/hcw2.htm">[2]</a> The winner was Antonio Ascari in 38 minutes, so very short race.
