No, but the break - at least as described by Singh - was different.
Visibly related to the Polish technique, but still quite different in a
number of important ways.

Yes; that's one reason I likened it to an R&D effort: D is tedious but
not difficult; R is difficult but not tedious.  (Again, this is a
drastic simplification.)

Neither is speaking of "the Enigma" as if it were a single thing. :-)
Enigma with how many rotors, drawn from how large a set?  With or
without day-key duplication?  Etc.

I would love to see a copy.
