5. Cipher Disk
It's tempting to think that spy gadgets aren't all that old, but even Caesar encoded messages using cryptography. This disk dates back to the Civil War, when it was used by the Confederate side — CSA stands for Confederate States of America. It's pretty obvious how the device works: rotate the inner wheel to displace the letters. M = G, P = J, etc. Simple to crack, right? Not if the message is written in a language you don't know. Spies were tricky like that.
4. Bulgarian Umbrella
A Bulgarian secret agent used an umbrella just like this one on a London street to kill Bulgarian dissident Georgi Markov in 1978. A standard umbrella was modified internally to inject poison into its target with the press of the trigger. In Markov's case, the umbrella contained a ricin pellet, which is next to impossible to trace. The museum displays a replica, made specially in Moscow for the collection. Boghardt says that in 1991, a room full of similar deadly umbrellas was uncovered in Bulgaria.
3. Pigeon Camera
It's a bird, it's a plane, it's a spy satellite! Before the dawn of aerial photography, pigeons did the job. Flying over enemy territory with a camera on autoshoot, pigeons could provide crucial information without getting lost along the way. Beyond photography, the birds also carried messages at times when radio communication was spotty or down. Pigeons sent through enemy fire up until the 1950s had a 95 percent success rate and were duly decorated with medals of honor for their service.
2. Tree Stump Bug
This tree stump bug used solar power to function continuously in a wooded area near Moscow during the early 1970s. The bug intercepted communications signals coming from a Soviet air base in the area and them beamed them to a satellite, which then sent the signals to a site in the United States. Solar power meant that no risky battery changes were needed. Nevertheless, the KGB discovered this green bug so the museum's copy is a replica.
1. Dog Doo Transmitter
Dog doo? Really? Boghardt says this, er, doohickey has a hollowed-out space inside, ideal for holding a message so that case officers and sources could communicate without raising suspicion. Doo tends to be left alone, which is why beacons disguised as tiger excrement were used to mark targets in Vietnam, Boghardt says. One of the risks is obviously that such a device would be thrown away or discovered by someone accidentally. "Accidents happened all the time," the historian says. "That's one of the challenges of being a spy or case officer."
