At least one example of the machine was installed at the British Tabulating Machine Company (B.T.M.), an organization that undertook the development and manufacture of the 210 massive and ingenious mechanical "Bombe" mechanisms (known internally by the company as the 6/6502 or CANTAB) used at Bletchley Park from 1940 to 1945 as part of the Colossus computer programme that helped to decoded enemy radio signals. B.T.M. also made an exact copy of the Lorch watchmakers' lathe.
