Well, the Discover article mentioned that there were *two* main mirrors
commissioned for Hubble.  One (the one that is to fly) from Perkins-Elmer,
and another (fate not mentioned) from Kodak.  The article gave a very 
in-depth chronology of the mirror, so I'm led to believe that the mirror
flying is in fact the original.

Anyone know what became of the Kodak mirror?
