There are actually four Ferraris seen in this photograph taken at the Coys International Historic Festival meeting at Silverstone in August 2001. The nearest car is a 1954 Ferrari 750 Monza (0568M) and next to that is a yellow 250 Testa Rossa of 1957 (0738TR). Car number 37 is a 1955 Maserati 300S, beyond that is a red Ferrari 166MM Barchetta (0040M) from 1950 and then a yellow 1956 Ferrari 500TR (0682MDTR). The red coupe beyond that is, I think, an AC Cobra.
The 750 Monza, which was introduced in 1954, was a 3 litre version of the 2 litre Mondial and was named 'Monza' after winning its first race at that circuit in the hands of Mike Hawthorn and Umberto Maglioli. The bodywork for cars was originally designed by Pinin Farina, but it is the later cars with Scaglietti designed bodies which are perhaps better known. This particular car spent most of its life in Finland, hence the Finnish flag on the headrest.
