The Manchester was the twin-engined precursor of the Lancaster. One of the troublesome Rolls-Royce Vulture engines is being worked on here. Unfortunately IWM do not provide known dates for many of their photographs, but L7279, the fourth production aircraft, was the first Manchester to be delivered to No 207 Sqn at Waddington on 6 November 1940 and the photo was taken soon thereafter. L7279 flew only a single combat mission before being relegated to training duties. Photo by: Bertrand John Daventry / Imperial War Museums
