Q is for Question Time - Seated Sailor Sitting Serenely

Prompted by the Pyro/Kleeware AFV figure which turned-up the other day, Chris has sent this to the Blog with a plea for more information . . .

A smiling sailor sitting, one assumes from a vehicle toy but was it plastic or a die-cast/slush-cast sort of thing? Or was it a boat or landing-craft toy of some kind . . . a DUKW or amphi-jeep; anyone know?

He's larger than the Pyro sculpt so it must have been a large toy and he's not apparently driving anything, so there may have been a bunch of them sitting in a row!
