Dambuster World War II Ray Grayston signed The Dambusters Lancaster Delivery Flights AJ N 1st May 1943 FDC PM Trafalgar Square London Route to Victory 1939 1945 1st May 05. Raymond Ernest Grayston was born on 13 October 1918 in Dunsfold, Surrey, and worked as an automobile engineer before the war. Like many young men of his generation, Grayston was fascinated by flying and volunteered for the RAF at the beginning of the war. In a TV documentary to mark the 60th anniversary of the Dams Raid he described how he loved riding a motorbike at speed, and that this was one of the things which encouraged him into the air force. Initially he served as ground crew but then, along with many others who were mechanically minded, he was selected to train as a flight engineer on the new generation of heavy bombers which needed more personnel. He was posted to 50 Squadron in October 1942, and teamed up with Les Knight, who had just formed a new crew. He flew on some 18 operations with this crew before they were posted en bloc to 617 Squadron in March 1943. Good condition. All autographs come with a Certificate of Authenticity.
