On 2 May 2012 I showed some photographs of the 1933 Napier-Railton which gave demonstration runs at the Richard Seaman Memorial Trophies meeting at Donington Park in May 2011. Here are some more photographs of the car I took that day.
You can see the three banks of four cylinders in these photographs, the exhausts for the right-hand bank (looking from the driving seat) emerging to the right of the engine and the exhausts for the central- and left-hand banks emerging to the left.
A pity the Union Flag's upside down!
The car is kept at the Brooklands Museum, and you can read about it here.
