Pete, These machines had a capability to put on and take off wheels. The Germans started out with one and eventually went to multiples. Some of the more complicated ones had more than four I think. The Poles copied the Enigma from a commercial model that was sold in Germany before the war and by the time the Germans invaded Poland they had a giant work shop think tank that was removed to England just in time to escape capture. It became a basis for breaking German codes. Time life produced a book on codes etc. That had a great article about this. Jerry Burney
