The photo on your website that you have labeled "Turing and Welchman’s Bombe (Photo: La bombe de Turing)" and named the image file as bombe-turing.jpg is actually a photo of a Navy Wave and a US Navy Bombe design and constructed by Joseph Desch et al in Dayton, Ohio on the National Cash Register (NCR) industrial campus in Building 26. This would be the Bombe that was used to decode the 4 wheeled Enigma. For the matter of accuracy - you may want to relabel and rename the photo.
