The 2nd Gran Premio Shell was open to cars up to 2l, and opposed some Ferrari 500 Mondial to A6GCS Maserati and OSCA MT4. Roy Salvadori was there with the Gilby Cooper-Maserati
and Michael Anthony in a Lotus-Bristol.
Among the A6GCS was chassis 2099, the 300S looking car, driven by Luigi Bellucci (race number #8).
Franco Bordoni #2 drove a new 200S, chassis 2401.
Now is the problem: Giorgio Scarlatti #46 had a car similar to the 200S. An other 200S ? Or a new 150S with a 2l engine ? Or a 300S with a 2l engine ?
