: It's 1967, and yes that is a Lotus 49, you are correct!

Much more likely to be 1966, because it's a Lotus 43 - BRM. The 43 only did one race in 1967, both Clark and Hill retired in South Africa.

Peter Windsor has a video of one being fired up at Goodwood (after the Spitfire aircraft demonstration)
