As for the BBC article saying it was only one of three

hard to believe. Thousands of Enigmas were built, and it's quite difficult
to believe that all but three have been destroyed.
The Computer Museum History Center <http://www.computerhistory.org>
has at least one, and I know that the NSA lobby also is reported to have one.
As the article points out, even Mick Jagger owns an Enigma machine, but of
a different type than the stolen machine.
I know about the 4-rotor and 3-rotor versions; what other types have there
been?
And, what is unique about the Bletchley Park Enigma that made it only one of
three in the world?

According to information linked to by the Wired article on this subject,
the missing machine was an "Abwehr" (sp?) variant, with no patch panel,
and extra symbols on the keys:

More details on the machine are located here:

And yes, there may be a few more around, but this one was one of three
Abwehr models _known_ to exist.
