'The Dambusters' film queries

Thanks to all of you who replied to my questions about ‘633 Squadron.’ I now have some questions relating to ‘The Dambusters’ in particular the camouflage applied to each of the film aircraft. As you probably all know the Lancs used in the film were B Mark VIIs which originally had light grey upper fuselage and upper wings and glossy black on the lower fuselage and lower wings. According to the book ‘Flying Film Stars’ by Mark Ashley only NX782 had a contrasting camouflage colour applied to the previously solely grey areas and the other three Lancs were left with light grey upperworks with no camouflage pattern. However according to Jonathan Falconer in his book ‘Filming the Dambusters’ all the Lancs had dark green/dark earth camouflage applied to the upper surfaces. Close study of the photos of the aircraft used in the film shows two colour camouflage on the upperworks though exactly what these colours are cannot be determined as all the photos from the film are in black and white.

Second question – what colour were the spinners of the film aircraft? Were they white or off white or some other colour? The actual ‘Upkeep’Lancs had black spinners.

Thanks for your help.

Best Wishes,

Colin
