Machine that sent Nazi messages up for sale

London: A machine used by the Nazis for sending coded messages during World War II will be sold at an auction here this month. It could fetch thousands of pounds at Christie's September 29.

The Enigma machine was used by the German military to send messages before the code was famously cracked, the Daily Mail reported. The Germans had believed the code was impossible to break.

It was originally produced by a Dutch firm after World War I and paved the way for modern computer systems.
