Wooden case by Mike Ledermueller
22 July 2014

Mike Ledermueller in Toronto took the completion of his Enigma-E kit a bit further than most of us. He went out of his way to add some super realistic features to it, and compare it to the real Enigma M4 on our website. Mike certainly has mechanical skills and has a very fine eye for detail.

The image on the right show the final results of his efforts and you have to look really well to see that it's not a real M4. Real keys have been added to the keyboard and the lamp panel has been raised somewhat. The displays are covered by an oval window, just like on the real machine.

If you wonder where the eight push-buttons for setting the wheels went: they are hidden under the top lid, and are operated by pressing the thumbwheel aside each display. At the top right, the 4V socket of the M4 has been replaced by the 9V DC socket of the Enigma-E, along with an appropriate note. There is even a real lock.

Mike got interested in the Enigma story after reading Simon Singh's book 'The Code Book' and wanted to posess at least a few parts of a real Enigma. When he discovered that this was out of his price range, he asked for an Enigma-E kit for his birthday and completed the project when his wife was away for work for several months.

For his replica, Mike used the M18340 from the Crypto Museum website as his reference.

Whenever possible, every detail of the M4 in the Crypto Museum collection was copied, including the small print. Please take some time to go through Mike's detailed photographs in his DropBox. They show all stages of building his kit and preparing a case for it. And watch the videos below.

If you wonder how he achieved all this, check out the detailed photographs in his DropBox. And if you have a few minutes, why not watch the time-lapse recording of assembling the Enigma-E PCB. It plays back at one minute per second.
