Tour suits are pieces of junk, they don't depict the real armor very well at all, if you have ever had a chance to view one in person NOT THROUGH GLASS!, actually touch them and see what they are made out of, and what is under the armor, you would agree with me, they are junk! I don't believe that many of the actual suits from the movie exist any more, besides the tour suits were made so that they are not able to be worn buy anyone which shows in the armor, in case one was stollen.
just observations from someone who has seen and inspected one in person
