There has never been a Bentley model known as the "Mark IV": neither from the "old" W.O. Bentley firm, nor from Rolls-Royce after the takeover of Bentley Motors in 1931. The "Mark IV" appellation seems to have been created by Ian Fleming, and erroneously perpetuated since. In contradistinction to the films, James Bond's official car in the Ian Fleming novels was a grey 1933 Bentley convertible. The car featured a 4.5-litre engine with the Amherst Villiers supercharger. In the novels, no gadgets were installed; this was Bond's personal vehicle that is mentioned in "Casino Royale" as being a hobby that Bond enjoys working on. Its only armament, in the novels, is a .45 Colt Army Special revolver Bond keeps in the glove compartment. The novel version of the Bentley Mark IV was destroyed during a chase sequence in "Moonraker". The Bentley is also the very first Bond vehicle seen in the film series, although it was shown very briefly during Bond's first scene in "From Russia with Love" and mentioned only in passing in "Goldfinger". In "From Russia with Love", the only gadget known to be included was a car phone, which in 1963 was very uncommon. The film version of "Goldfinger" strongly implies that the Bentley was issued to Bond by Q-Branch, since he asks Q about the vehicle, only to be told that it had "had its day". He is given the Aston Martin instead.
