Porsche 550 Spyder

I took this photograph at the Coys International Historic Festival meeting at Silverstone in July 2000, but I don't remember if it was part of a display or one of the vehicles in the Coys auction which took place during the weekend of the meeting.

It's a Porsche 550 Spyder, about 90 of which were produced between 1953 and 1956, not many of which had a headrest as seen on this car. The Porsche 550 had a 1,498cc flat four air-cooled engine and dominated the 1½ litre class in sports car racing in the mid 1950s.
