M-209-A CIPHER MACHINE


United States Army M-209-A.

US Army M-209-A cipher machine, serial number 9357,  in complete and working condition. Includes original canvas case, all accessories, manual, and spare paper tape.

This is a very fine example of an M-209-A from World War II that shows evidence of being used in the field.Signs of wear and use are evident on the metal case, canvas carrying case, and the machine itself and are characteristic of machines that have seen use with troops in the field.

The identification plate reads: “Signal Corps U.S. Army Converter M-209-A, Serial No. 9357, Order No. 1499-Phila-42, Supplied By Hagelin Cryptograph Company, New Milford, Conn.”

The M-209-A is a portable hand-operated mechanical cipher machine developed in 1940 by Boris Hagelin in Sweden for the US Army. This rotor-based cipher machine does not require electricity and is lightweight and durable. Therefore, it was perfectly suited for tactical front line use. While the code generated by the M-209 was not as strong as the Enigma code, and was generally being read within 4 hours by the Germans, it was considered secure enough for tactical messages that were of no value after that length of time. The US military used the M-209-A in both the Europe and the Pacific during World War II. The M-209 cipher machines were easy to use and produce and were used by the US Army well into the Korean War.

The M-209-A machines were manufactured under license from Hagelin by LC Smith Corona Typewriters, Inc., in Syracuse, New York. The machines were supplied with a canvas carrying case, paper tape, and an operator’s manual. Inside the metal case lid were more paper tape, an ink reservoir, lubricant, an adjustment screwdriver, and a pair of tweezers for feeding the paper tape through the machine.

M-209-A, serial number 9357, is located in the United States. Price does not include shipping.

Complete M-209-A cipher machines are rare, even more rare is an M-209-A with evidence of use in the field. However, we do often have other M-209 cipher machines available for sale. Please feel free to contact us directly for more information and pricing.
