That is ex-pat kiwi Roger Wills' car. Still a Lotus 15 with 1960cc engine and yes, a laurel wreath on the bonnet.

That was the last race on the Saturday at 5:50pm, but I was knackered by then (I'd been there since 7:15am and was still hobbling with a badly sprained ankle so got away before the crowds built up. Sad (for me) that every year, they have that as the final race of the day, so I have yet to catch them other than in practice and it is one of my favourite race groups.
