Interesting portable 'Ambassador' model portable polygraph machine built by the Lafayette Instrument Company, housed in its original 21Àù x 13.5Àù x 6.5Àù metal suitcase. The lid opens to reveal the five-channel, all mechanical polygraph with two pneumographs, one galvanometer, one cardiograph, and one stimulus marker. Untested and in fine cosmetic condition, with some wear to the case. An interesting visual piece that evokes the spy games (tradecraft), espionage tactics of the Cold War, and law enforcement 'lie detection.'
