1929/36 Riley Special

I took this photograph at Lodge Corner during a Four Lap Scratch Race at the Vintage Sports Car Club's Richard Seaman Memorial Trophies meeting at Oulton Park in June 1993.

I didn't make a note of which car it was at the time, as usual relying on identifying it later from the programme of the event. It's obviously a Riley Special, but there were five of these in the race and you can't make out the car number in this photo. It looks like the number is on the scuttle and tail of the car though and the only car which matches the bits of number you can see is 47 which was the 1929/36 Riley Special of F C Roberts which was driven in the race by D M Robinson. That would seem to be a 1929 Riley Brooklands with the 4-cylinder inline 1,496cc engine from a 1936 Riley 12/4.
