This car is said to be a Moretti factory Single seater that was built for Formula 750 Races in 1956. "It was able to compete in a few of the First races of the Formula Junior Championship created in 1958, but without any significant result to speak of". (source: Moretti, Alessandro Sania)
There was a "Corsa 750" category to race in during 1954. It had its origins as an Italian version of Formula III which was limited to 500cc in England, where it originated. Chassis 1356 was built as a monoposto and seemingly first appeared at the Coppa Michelin (Torino) 10 April 1954 without paint. I do not yet know who drove it there, but I have some negatives from Bertazzini that show the car (race #16) and the driver quite clearly. (Source John de Boer)
This model had a front twin-cam engine and a Ferrari-Angiari chassis of square tubing.
This car was bought by one of its previous owner directly at the factory Showroom in Torino in 1976 where it was gathering dust
The owner listed the car in serval Hill Climb races in the early 80's (Mont Ventoux), it was subsequently sold
