unknown greenhouse help- pictures

[dogsndolls2]

I posted earlier about my Florada GH, but my photos didn't work. Hopefully these will come through better. One is the whole thing, one is a vent or window that looks like nothing I've seen before, the third is a cross section view of what I assume is part of the (swinging) door frame, but can't figure out how it attaches. ANY help is appreciated.
