I imagine a ton of boat activity nearby back in the day, so my guess is some kind of boat/pulley hardware but I cant seem to find any matching examples.
The one end without the screws has a piece that spins around.
Can you post a side view of the piece that spins around?
It appears that the end with screws was attached to 1/2" thick board.
Not strong enough for heavy lifting. So maybe not a pure "pulley" in the way we commonly think of it's use in straight heavy lifting.
