This is a photograph I took in the paddock at the British Empire Trophy meeting at Oulton Park in April 1957.
It's the Ecurie White Rose team's Lotus Eleven Le Mans of Alex McMillan which had a 1,096cc Stanguellini engine (the programme of the event says that it's a 'Lotus-Stranguellini'!). There were three heats based on engine sizes and he finished in 22nd place in the overall standings.
