Stereoscope, Universal, Type SV-3. Used by photo-reconnaisance staff to view aerial photographs for interpretation purposes. The use of these helped to ascertain accuracy of bombing, pinpointing targets and so on. This 'reflection' stereoscope provided greater, clearer and more comfortable magnification than the small 'pocket'sized Type D. It features a grey painted steel frame to which a binocular head, type TL3, could be attached providing a four times magnification. The frame also holds two mirrors that were carefully angled such that they reflected the images being viewed into the binoculars. Fitted with folding legs, one adjustable at the bottom to allow for uneven surfaces. The war department broad arrow marked binocular head, by Kershaw Opticals of Leeds, has rotating eyepieces for prism adjustment, allowing for individual differences in eyesight. It is mounted on a plate which, when attached to the frame, allows the binoculars to swing in and out of position as required for use. Condition is very good and the stereoscope comes in its original fitted wooden case with 2 spare large and small mirrors and lens dusting brush. The box is a bit worn/scratched and the lock key is absent. These larger stereoscopes were designed for the stereoscopic viewing of overlapping stereoscopic pairs of aerial photographs and used from late 1942 at RAF Medmenham, home to the photographic interpretation unit. An impressive display piece. Stock code M26371.
