An early Naval Enigma model (the "O Bar" machine) had been solved before 1931 by the Polish Cipher Bureau, but it did not have the plugboard of the later standard Enigma. Mahon (1945) cites, as his source for "most of the information I have collected about prewar days", Alan Turing, who had received it from the "Polish cryptographers", who Mahon says had done "nearly all the early work on German Naval Enigma [and] handed over the details of their very considerable achievements just before the outbreak of war."^[24] Mahon, A.

Some writers, after Bloch & Deavours (1987), argue that Rejewski is more likely to have received these documents in mid-November, rather than on 9 or 10 December 1932. Rejewski, however, recalls: "I later... learned that... it was on 8 December, [1932, that] Bertrand had come to Warsaw and delivered this material. [H]e describes it in his book [Enigma. T]here is a mistake [in the book] and he gives the year [as] 1931. But later I corresponded with him, and it turned out that it had been... the eighth of December, 1932."^[37] Bloch, Gilbert; Deavours, C. A.
