Rotors

This type of Enigma machine came with 5 rotors (I, II, III, IV, V). Three could be placed into the machine at any one time. The others usually had a separate box for transport.

Tony Sale's site: Tony Sale was one of the key figures in the effort to preserve Bletchley Park. His site has a wealth of information on numerous topics, such as the effort to rebuild the Colossus machine. You can buy DVDs of him delivering lectures as well.
Enigma-E machine: This is the coolest thing ever! Order this kit and you can build your own Enigma! Be sure to check out the Enigma form generator page as well. In fact, I highly recommend the entire site. These guys know their stuff.

Tatjana van Vark built an amazing Enigma-like coding machine. It shares the same basic principal as the Enigma, but also has numbers and punctuation marks in addition to letters. You really have to see it to believe it!
Enigma page at The Best Links: This site has a good amount of information, plus some very nice CAD drawings.
