Tom, W1TP is in our club, The Green Mountain Wireless Society. As a leading authority on cipher machines and the Enigma in particular, he gave a most excellent talk about the Enigma Machine at our last meeting. I had occasion to view his site lately and if you ever wanted to see an incredibly comprehensive collection about telegraphy and all of it’s many facets, look no further.
