old harpoon shape wrought iron hooks double hangers, antique vintage farm tool or implement hardware

Interesting very primitive old 'hooks' of some sort - I don't know exactly what these are / were, but they'd make good rustic style hardware to upcycle I think! The wrought iron hooks are about 11" long, 13" long including the bracket.

There's three brackets (two hooks on each) in this lot, as shown. Very sturdy, very rustic, rough and rusty. They're just as found out of a farm estate here in Wisconsin.
