The Commercial Section was set up in 1938. It moved location four times: from London to Bletchley at the outbreak of war and back to London in 1939, because of pressure on space at Station X; in September 1940 to a house some miles from Bletchley; and back to London in May 1942 as part of the Civil Branch of the school. The section was closed down in August 1945.
