replies: text: Hm, interesting. Thanks, I should've looked it up myself. Maybe Beesly's "Who Was the Third Man at Pyry?" in Cryptologia is based on some research of the British archives and confirms either version. It would be also interesting to learn what happened with the information gathered by Knox upon his return to Britain. He must have written a report of the meeting i presume (but obviously I don't know what the procedures were, so he may have not as well, or it was destroyed). Lysy 08:46, 18 Apr 2005 (UTC)
replies: text: It is generally accepted by serious historians (e.g., see David Kahn's Seizing the Enigma) that the third Briton at the July 1939 meeting was Commander Humphrey Sandwith (spelled with a "t", not a "c").  You won't find most of the above material in the Polish editions of Kozaczuk's 1984 book, which reprint only one of Rejewski's papers and don't contain Woytak's interview.  The same, incidentally, may be said of Kozaczuk's posthumous 2004 Enigma, except that it doesn't include any of Rejewski's papers and actually perpetuates the Menzies-at-Warsaw myth.  logologist 10:26, 18 Apr 2005 (UTC)

message: I would think that any decent historical cryptanalyst would take issue with the wording on the caption on the German Army stecker board.  The board's configuration added very little additional security (which primarily was thought to come from the changing configuration of the rotors). --enm 19:15, 27 Dec 2006 (UTC)
replies: text: As I understand it, that was not the case, and the caption is correct. Which decent historical cryptanalysts do you have in mind? — Matt Crypto 20:50, 27 December 2006 (UTC)

message: In the background section, it says "and the settings of the stecker plugboard".  "Stecker" is German for "plug", so isn't this a redundancy that isn't needed?  Bubba73 You talkin' to me? 22:34, 7 April 2018 (UTC)
