This car participated in a round of the Shell Ferrari Maserati Historic Challenge series at the SeeRed meeting at Donington Park in September 2004.
The blue car is Stephen Dudley's 1950 Ferrari 166/195, which I've featured before, on 6 September 2013, at Silverstone. The car was originally a 166, but was converted to 195 specifications in 1951 and is chassis #071S. The car behind it is the 1951 Maserati A6GCM of Julia de Baldanza (#2033) and in front is the 1958 Ferrari 250 GT LWB TdF of Conrad Ulrich (#1141GT). The photograph was taken at Redgate corner.
