The DV-505 is Voice Security System and one known place of use was the Falklands War in 1982. Apparently British intelligence broke the cyphering system. All this according to the copy which accompanied the artifact when it was up for auction on E-bay. It was an American designed device and sold internationally.
Does anyone have more information about this device?
