1956 Aston Martin DB3S

I took this photograph at Luffield corner during the 1950s Sports Car Race at the Coys International Historic Festival meeting at Silverstone in July 1998.

Leading is the 1956 Aston Martin DB3S of Tony Smith followed by Adrian Hall's 1955 Lotus Mk X. The car on the right looks like it may be the Lola Mk1 of Irvine Laidlaw.

1964 Porsche 904 GTS

I took this photograph in the paddock at the Coys International Historic Festival meeting at Silverstone in July 2000.

It's the 1964 Porsche 904 GTS with which Irvine Laidlaw and Andrew Kirkaldy competed in the 50 minutes long Coys of Kensington Pre 1964 GT Cars race. The Porsche 904 was introduced in 1964 with a 1,966cc flat-four engine and the 1965 car had a variant of the Porsche 911's flat-six engine of 1,991cc. A few cars were built with a flat-eight engine of 1,962cc based on the engine of the 1962 804 F1 car.

Porsche 904/6

This car competed in the 90 minute long Historic Motor Racing News Gentlemen Drivers GT And Sports Endurance Race at the HSCC's Gold Cup meeting at Oulton Park in August 2005.

It's Irvine Laidlaw's 1965 Porsche 904/6, and he shared the driving in this race with James Diffey. The original Porsche 904, introduced in 1964 had a 1,966cc flat-four engine but the 1965 car had a variant of the Porsche 911's flat-six engine of 1,991cc. A few cars were built with a flat-eight engine of 1,962cc based on the engine of the 1962 804 F1 car. Irvine Laidlaw's car is chassis 906-012 and was originally a Porsche works car that took part in the 1965 Le Mans 24 Hour race driven by Günter Klass and Dieter Glemser, but it failed to finish, retiring after 16 hours with a broken camshaft.

On 2 May 2015 I showed a photograph of Burkhard von Schenk's Porsche 904/6 that I had taken at Donington Park in 2004.

Porsche 906

This car competed in the Coys of Kensington 80th Anniversary Trophy for Pre-1972 Le Mans Cars race at the Coys International Historic Festival meeting at Silverstone in July 1999.

This is the 1966 Porsche 906, also known as the Carrera 6, of Irvine Laidlaw and was driven in the race by Andrew Kirkaldy. The 906 has a flat-6 1,991cc engine and was introduced by Porsche in 1966 to replace the Porsche 904 which had a flat-4 1,966cc engine. The extra power of the new car was needed to compete with the Ferrari Dino 206 SP in the 2 litre class of racing.

I've shown photographs previously of the Porsche 906 on 24 February 2015, 26 October 2015 and 2 May 2017.
