 The films storyline deals with the Lektor Decoding Machine, the  name of which was called the Spektor Decoding Machine in the  original Ian Fleming (I) (qv) novel. Its name was changed because  of its similarity with the name of the fictitious criminal spy  organization "Spectre". He based this device on his knowledge of the  Enigma Decoding Machine from World War II. Fleming was involved with  the Ultra Network who cracked the Enigma Code in 1939. The Ultra  Networks activities were not released until 1975 in a book called  "A Man Called Intrepid". Flemings friend Sir  William Stevenson (III) (qv) wrote the book which was published at  the time when the closed period on wartime secrets expired and the  records were finally declassified. The book was subsequently filmed  as a television movie in 1979 (See:  _"Man Called Intrepid, A" (1979) (mini)_ (qv)).
