The Lektor
This
is a typewriter-sized Soviet decoding machine desperately desired by MI6. Housed
in the Soviet embassy in Istanbul, the Lektor is the bait used by SPECTRE to
lure Bond into a deadly trap. Curiously, the device is called the Spektor in
Fleming's novel, wherein the villains are SMERSH agents. Because Bond's adversaries
onscreen were from SPECTRE, the device would be confused with the criminal organisation.
Thus, the screenwriters changed the decoder's name to Lektor.
