What are these?

[dave]

Any insight or alternate uses are welcome. I found these two sets of hooks while cleaning out an area of my shop that I haven't touched since the previous owners sold the property to me three years ago. They're iron, and the hooks aren't very sharp at the point. Given I live in cottonport, I think they may have been used for weighing cotton bales, but they seem small for that. Maybe some old small game skinning gambrels? Obviously they pivot in the center tho. One is slimmer than the other.
