Item is an early model of the subminiature Micro 16 camera. It uses 16 mm film in special cassettes and a cartridge to cartridge fed. The camera uses a Achromatic doublet f8 lens and a single-speed shutter. The early model was produced from late 1946 to mid-1947 and uses an aperture selector level with a raised metal arrow with a checked background. The aperture selector switches between "Bright", "Dull", and "Color".
