Thanks for everyone replies so far
Branson, My grandfather owned a fence construction company. Technically, the workroom we cleaned out was my great grandfather's, but it was just off of the shop at my grandfather's company. My great grandfather liked to tinker around with a lot of different things, so it's probably no fence related. My uncle owns the company now and doesn't recognize it.

The top arms naturally hang down like this.

You can push the arms up like this, and they'll stay. However, they wont stay up until you get it up to this point. A piece might be missing or something though.

This is the bottom of the base

it unscrews like this

and the bars come out so it can fold up

Here it is folded

upon further inspection I realize it does have something written on the bottom. I can't really make it out though, but here it is.
