Secret Services & Postage Stamp

The challenge this time is: choose a stamp that talks about the blog theme... and what's better than The British bombe?
It was a wonder of mechanical and electrical engineering. It's function was to figure out the rotors settings for each day's keys, and it was capable to perform that operation in at most 12 hours. From that point, all messages could be read in real time. In all, 210 British bombes were built during the war and all were destroyed at the end of the war, but few of their american evolution, used for analysing all combinations generated by 4 rotor Naval Enigma, in all 121, are still intact and they are still here, remebering us of what a great step toward artificial intelligence it has been done during that period thanks to these machines.
