At the Silverstone Historic meetings I went to in the 1990s and early 2000s David Piper was usually present with a few of his stable of Ferraris. The photographs below show the cars he took along to the Historic Festival meeting of 2001.
1967 Ferrari 330P4, serial number
0822
1964 Ferrari 330P2, serial number
0836
1964 Ferrari 365P, serial number
0824
1967 Ferrari Dino 246S
1964 Ferrari 275LM, serial number
8165
The photograph below, which I took at the 1965 Tourist Trophy race at Oulton Park, is presumably of the same car, although at that time it was labelled a 250LM. The Wikipedia entry for Ferrari says:
'Only the very early LM's were true 250 models, with all the rest made as 3300cc models and as such should have been named 275 LM (the early cars were also converted to the 3300cc engine).'
Correction: The car in the 1965 Tourist Trophy race in 1965 was
5897, now owned by Englebert Stieger.
