Expo Cameraco. Expo Police Camera

{"overview":"The Expo Police Camera is an early 20th-century subminiature still camera made by Expo Camera Co., designed in the form of a pocket watch so it could be concealed in the palm of the hand. Condition, completeness of the original film cassette, and presence of the maker's case heavily influence what one of these sells for today, and the scarcity of clean examples explains why the price spread is so large in the auction market.","buying_guide":"Inspect the watch-style body for dents, plating loss on the crown and bezel, and a clean, scratch-free meniscus lens behind the front aperture. The original film spool\/cassette is frequently missing and is the single biggest factor in value, so confirm it is present; also check that the shutter still fires and that the viewfinder sight on top is intact.
