Stereoscope for aerial photography by Huet Paris from Israeli military surplus, used by mostly intelligence units to read and decipher aerial images of enemy territory and military related material by having a three dimensional image for better understanding. This Stereoscope by Huet Paris from IDF surplus is in very good condition, marked with the Israeli military marking of the צ letter (Tzadik) and a נ inside the Star of David signifying that it has been checked and approved for use. The right eye lens can move left-right as to fit the viewers face and providing a sharp 3D image.
This is a rare piece of Israeli military history as well as militaria history, signifying how enemy maps used to be deciphered by intelligence personnel so that every enemy tank, aircraft, artillery piece, base, bunker, and others can be identified. This was how it was done before the wide use of satellites and high-tech computer imaging and deciphering programs.
