London and Malta, April 2012

There were more than 200 Bombes like this one working in Britain in WW II and more than 100 in the USA. As I understand it, they were set up to try a limited number of possible settings of the Enigma machine used by Germany. The limited subset was determined by human guesswork. After the war all these machines were destroyed, and this one was built by volunteers 1996-2007. Full details at http://www.jharper.demon.co.uk/bombe1.htm.
