The Bolingbroke was intended as an improved version of the Blenheim but immediately pre-WWII the British were in urgent need of actual plane numbers on the ground rather than down-the-line projects. Development was handed over to the Canadians and the end result was 626 Bolingbrokes produced between 1939 and 1943. This example is under restoration at the National Museum of Flight, East Fortune and is actually a composite aircraft using the fuselage of 9940 with the wings of 9049.
