One of the several images that Ford of Britain has dug up from their archives to celebrate their centennial is the one above, in which Ford workers are assembling Rolls-Royce Merlin engines. The aero engine assembly didn’t take place at Dagenham, rather at the factory in Trafford Park, Manchester, that Ford opened at the request of the British government to build the engines under license engines for the RAF. The Luftwaffe apparently bombed the factory a few days after it opened in May 1941, but it appears the plant was able to continue building engines because it was designed in two separate sections to minimize the effects of a bombing.
