It has arms that move and looks like it screwed on to something. Any ideas

Wow, I am keeping tuned to find out! You found two of them?

I'm usually pretty good at figuring out one of these knurdlers, but this one has me scratching the bald spot on top of my head. Looking forward to the answer. Very cool, very interesting.

I used to have a parasol in my backyard as a kid. Looks like the folding metal part.

It reminds me of old time dish cloth hangar , screws to the wall and folds flat when not in use. The rods are missing. However for that application using cotter keys would be odd.

Looks like brass and no markings. The ends of the arms have threads
