I've found a few sources in which the name of Giulio Cabianca is reported to be originally written as Casabianca.
I do not know whether his family name was actually Casabianca and he shortened it (for unknown reason), or it was simply typing mistake...
A native of Verona, Italy, Giulio Cabianca was a talented sportscar driver. He won the Dolomites Gold Cup in 1956 in a works Osca MT4 1500, and took part to four Formula 1 Grands Prix between 1958 and 1960.He lost his life in a bizarre accident while testing a Cooper-Ferrari F1 at Modena Autodrome .
