couple things.. you probably are aware but the basic enigma had 3 wheels, the naval version..tougher.. with 4 wheels.
Canada captured an enigma, but it was in 1944 and by then several others had been already been captured.
From what I understand, Turing's "Colossus" is considered to be the first true programmable computer, beating out Eniac which was only working properly by 1946 and which was outdated by then.
The American film of 2000 called U-571, and capture of an enigma was well received by the American public and critics, in spite of the fact it was riddled with ridiculous factual errors.
The film was even brought up in the British parliament as an affront to British seamen..and then Pres Clinton had to write a letter to the Brit PM saying the film was fiction. Although the filmakers were urged to include a disclaimer that the film was entirely fiction, and note the British captures of enigma, they declined the "fiction" note, but did add info at the end about the British captures of engima.
