. Some of the cryptanalysts had joint appointments with the Testery. in Initially in June 1943 the section was small: Good, Mitchie, two engineers and sixteen Wrens in a small hut. By the end of the war there were 26 cryptographers, 28 engineers, 273 Wrens with ten Colossi, three Robinsons, three Tunnies, plus twenty small electronic and electrical machines.
