In the early Twenties, Ugo Zagato met the brilliant Alfa Romeo engineer Vittorio Jano, with whom he found himself in accordance: Jano wanted to build Alfas that won races and therefore needed the best suppliers. That was the time when young Enzo Ferrari started his career as a driver of Alfa Romeos.
In 1926, with the Alfa Romeo 6C (conceived by Jano), Zagato officially became the coach builder of choice for racers by the Milanese manufacturer. So the Alfa Romeo 6C 1500 Mille Miglia Speciale, winner of the 1928 Mille Miglia, the 6C 1750 SS, winner of the 1929 edition, and the 6C 1750 GS, that in the hands of Nuvolari got onto the highest step of the MM podium in 1930, had all bodies designed by Zagato. The Drake, in the meantime, gradually discarded his racing helmet to don the managerial suit and tie, until, in 1929, he founded in Modena the Scuderia Ferrari, the private team of the official Alfa Romeos. He chose Zagato as partner for the supply of bodies. Thanks to the Alfa-Ferrari-Zagato joint-venture, some unforgettable pages in the history of automobile competitions were written. The Alfa Romeo 6C 1750 Gran Sport, top racing version of the 6C at the time, was also available with a 1.5 litre engine, so that it could race in the lower classes.

Chassis 10814406, built in 1933, is one of 18 equipped with a Testa Fissa engine, that is with a solid head and cylinders to prevent the cylinder head gasket wear during intensive use. Bought new by well-known Italian lady driver Anna Maria Peduzzi (known as “Marocchina”), it was extensively raced in the Thirties. It took part in the 1934 Mille Miglia for Scuderia Ferrari. The driver Anna Maria ‘Marocchina’ Peduzzi and co-driver Gianfranco Comotti finished the race thirteenth overall and won the class Sport for cars with engines up to 1.5 litres. It come back in 1936, driven by Swiss Emmanuel de Graffenried (DNF).
In 1953 it was imported to the USA by Luigi Chinetti (the famous Ferrari importer and owner of the NART - North American Racing Team).
