This is the 1957 Aston Martin DBR2 of Simon Draper and was driven by David Clark in the race.
Only two Aston Martin DBR2s were built, and this is DBR2/2.
This is the other DBR2, driven at Silverstone by the owner, Steve O'Rourke, it's DBR2/1.
A blog largely about photos I've taken over some years of classic and historic racing and sports cars.
