This is an original WW2 cipher machine / enigma machine made by Smith & Corona Typewriters. This small device was used by the Signal Corps during WW2. The box measures 7x5x3.5 inches. Has original paper inside, along with a small maintenance screwdriver. The gears are all a little tight, but this does seem to still be fully functional and in great overall condition. All of the gears move and rotate properly. A cool piece of US military history. See photos before bidding and feel free t...o ask any questions. Buyer pays $40 shipping USPS priority mail.
