There were different Enigma versions, even at the same time the different German organizations used simpler or more complicated versions (there were 4 or 5 iirc for Navy, Army etc) the Polish broke an earlier model and Turing's team broke the Navy one (more complicated than the one Polish broke, but simpler than others), why can't journalists read a book or ask someone who read a book before publishing?
