The Zorki-6 'Reflex' Spy Camera: A 'Zorki-6' in reflex casing and with tubular lenses [#674068 - indicating that it was camera #68 manufactured in 1967] for 'through-the-wall' spy photography. Designed for silent operation and installation by 'technicians' employed by the Kgb. Contained within the Zorki-6 body is a double optical group, mounted and fixed to the inside wall of the reflex casing. The mirror, situated at the centre of this group, acts as the shutter which is opened and closed manually by the trigger at front right. The viewfinder, with dioptre correction, monitors a formed image, circular and uninverted. The extension tube also contains an optical group. In as new condition. A remarkable piece of secret equipment from the height of the Cold War era! [Ref: 'The Authentic Guide to Russian and Soviet Cameras' by Jean Loup Princelle, Hove Foto Books, 1995.]
