Came from a neighbor that just moved away. Previously lived in Roanoke, Vermont and Florida. He thinks he got it with a lot of tools from an estate sale. Neighbor was into sugaring, (helpful or a red herring?). Bolt is screwed into where nut is which means the head didn’t cross the line where the two angle iron pieces meet. Bolt is not stamped so not graded. Metal disc tilts back and forth, no signs of anything being threaded through the holes.

Thoughts?
