" Putin uses typewriters."

Like that's secure...

"Key escrow does not make you more vulnerable to a 3rd party?" You have got to be kidding me. YES IT FUCKING DOES. Repeat after me: KEY ESCROW IS SHIT. Here's an excerpt from a paper detailing why it is such a bad idea right out of the gate:

In short, eavesdroppers seeking access to the session key must use two keys to decrypt the LEAF: the family key (which is common to all chips) and the chip key (which is different for every chip). Assuming that the family key will be in fairly wide circulation,{194} the security of the Clipper Chip stands or falls on the security of the master list of chip keys. This list, or the two lists of key segments, would be of enormous value to any attacker, such as a foreign government bent on industrial espionage.

Oh wait, nevermind.

Anyone got some chalk and slate?

History?

The real history is that the UK found it didn't have the resources to fund Bletchley Park without American help and by the end of the war most of the work was being done in the US:

By December 1943, 120 machines were installed. For the remainder of the war, the US took care of breaking the majority of German Naval Enigma traffic and in particular the messages of the dreaded German U-Boats.

SIGABA was weak...

Unless you know something that I don't, SIGABA was never broken in its relatively long service life for the US.

SIGABA (ECM)

SIGABA was a US cipher machine based on the electromechanical rotor principle. It was developed in the late 1930s as a joint effort of the US Army and Navy [1]. At the time it was considered a superior cryptomachine, intended to keep high-level communications absolutely secure. It was used throughout WWII and was so reliable that it was used well into the 1950s, when it was replaced by machines like the KL-7. As far as we know, SIGABA was never broken.

http://www.bletchleypark.org/news/docview.rhtm/675670 says the red capsule attached to the pigeon is an Allied capsule, so if the code is German the message is from a German spy.

It's more likely the code is British. It has "AOAKN" twice - once at the start and once at the end, and from the digraph frequency (below), "AO" "FN" and "AK" stand out. I think that rules out any Enigma-based codes (e.g. the British TypeX), as well as the US SIGABA - the AOAKN would not be repeated at the beginning and end. I haven't found a description of BAMS yet.

2 UA
2 OA, 2 AK, 2 KN (this is AOAKN twice)

Hooray for the russians!!

The Photo Sniper was initially made for the Russian market. The text on the camera body, on the pistol grip and on the container was in Russian. ÐÐzÐÐz ÐÐÐÐ(TM)ÐYÐÐ means FOTO SNAIPER (Photo Sniper). The container was usually painted in the typical Russian grey hammerite colour.
