It is peculiar to think that if the films had been as the books, Bond would have driven a 1931 Bentley Blower
The first books were published in the early 50's so I suppose it might not have been too incongruous then but certainly would have looked very odd in the swinging suave 60's of the films
A few years ago I was convinced I'd seen a Morgan in a Bond film but it turned out to be a Brazilian MP lafer in Moonraker - looked a bit like an MG T
