I've shown photographs (on 17 Jan 2016 and 26 Jan 2016) of Rileys in the paddock at the VSCC's Hawthorn Memorial Trophies meeting at Oulton Park in July 2015, and here are some photographs of Rileys in action on the track that day.
This is Race 1 and it's Durward Lawson's 1937 Riley Special at Knickerbrook on the short Fosters Circuit.
Race 1 again and it's Greg Lerigo's 1932/35 Riley Special at Knickerbrook leading Malcolm Underwood's 1937 Delahaye 135
Still Race 1 and Dr David Pryke's 1935 Riley 12/4 TT Sprite Replica heads up Clay Hill towards Druids Corner.
Here's John McAvoy in Race 1 in his 1936 Riley 12/4 Special on his way up Clay Hill
This one's Race 4 and it's David Lamb in his 1929 Riley Brooklands at Druids Corner
Again at Druids Corner and this time it's Andy Bush in Race 5 in his 1935 Riley TT Sprite Replica
