Saw this and keep thinking of combining the "switch" artifact with the 90* bent "gidgy". Perhaps the plastic scalloped piece is just a crest or something on the outside of a case?

This is for hanging clothes in a 40s/50s piece of American Tourister luggage (suitcase)
I don't know if the scale would work out, but it seemed the shaft on 2-6-s-32 was very similar to the diameter of the hole in the gidgy. How the knobby end gets through I don't pretend to know.
I was wondering if the makeup/mirror/gidgies, etc weren't all part of an old luggage makeup case, perhaps an Earhart brand piece. The marketing for the Earhart luggage touts it as handmade, as the gidgies might be. There are "garters" inside those old makup cases for holding bottles and the like against the edges of the case. My theory was that perhaps the serrated edge of 2-6-S-03A & B artifacts were for holding a "garter" in place.
I'm working on sourcing one of those and will post up if I find anything interesting. I'm having a difficult time finding anything of the proper vintage...
