That Phantom 20 looks like Stuart Evans old boat, must be the most polished boat in the world, whenever I was at Stuarts House he was always polishing it, treated it like a baby.
Definitely Stuarts old Phantom he sold it to a Whitsable member some time ago long after he bought the F1 Twin Conely, good boat and was well looked after by Stuart, originally bought new from Bert Williams at BJW Automarine in South London.
