What is this bronze thingy ?

[MtyQuinn]

I don't recall where I found this piece of bronze. Either California High Desert So. Cal. or Superior AZ. By the the look of the patina and odd shaped tool it has a pin on one end like a clevis and half round on other. Any ideas.

Neat, whatever it is.

Almost looks like a window vent opener that uses a cam to lock it down and i am thinking from a boat ?
