i assume that the other three went to people who used them in comic stores/rentals/some non-air-proof case. in all these cases, without wax (lol alot like turtle wax) these things have dry rotted to dust. a special wax is used on ancient swords and armor to keep them from rusting. however, the stuff is stiff, and would render any costume impossible to wear. it would be like wearing a wooden costume, not a rubber one. the one restored was never taken out of it's air-tight tin and it was still in bad shape. how did that one escape from never being taken out of it's tin after paying all that money? to never look at it? that would be a story in and of itself.
