I think #3 says "Take Porthole Window to Spiral for shelving".

As for the glasses, while it does slightly validate my hypothesis, I think it was just made for the set tours and, as far as canon goes, treating it they way you did is probably the best way to go. it does fit Mtka though, given how many times she's had to deal with such artifacts.
