 * National Cryptologic Museum, Maryland, US exhibits a machine.
 * The Deutches Museum, München, Germany have a Lorenz SZ42 on display.
 * The Heinz Nixdorf Museums Forum, Padeborn, Germany.

M-209
The M-209 (Wikipedia), designated CSP-1500 by the US Navy, is a portable, mechanical cipher machine used by the US military primarily in World War II, though it remained in active use through the Korean War. The M-209 was designed by Swedish cryptographer Boris Hagelin. M-209's can be found at:
 * The Royal Signals Museum, Blandford Camp, UK, which has three M-209-B's on display.
 * The International Spy Museum, Washington DC, US.
 * The Heinz Nixdorf Museums Forum, Paderborn, Germany.

NEMA
The NEMA (Wikipedia) (NEue MAschine) ("new machine"), also designated the T-D (Tasten-Druecker-Maschine) ("key-stroke machine"), was a 10-wheel rotor machine designed by the Swiss Army during World War II as a replacement for their Enigma machines.


 * Intelligence Corps Museum, Bedfordshire, UK.
 * Bletchley Park, UK.

SIGSALY
SIGSALY (Wikipedia) was a telephone scrambler used in World War II for the highest-level Allied communications. The machine also pioneered digital communications, including the first transmission of speech using pulse code modulation.
 * The National Cryptologic Museum, Maryland, US &mdash; a mockup of part of a SIGSALY terminal.
 * Cabinet War Rooms, London, UK. The museum contains the Transatlantic Telephone Room (a converted broom-cupboard) where Winston Churchill was able to connect to a SIGSALY installation for secure transatlantic communications ; the actual SIGSALY machine was located elsewhere.
