Help. Could this be what it looks like ?

I am deeply sorry this object is not connected with gunnery or even with restraint devices, thus missing its collecting interest.
It took me eighty miles around country, partly under heavy rain, through some six farm wind mills completely abandoned and missing their machinery, till i found one in working condition, where we can clearly see that the discussed ball and chains belong to that kind of apparatus.
The pictures are penalized by the weather conditions, but it's all there; the upper ball suspended by two rings, and the intermediary ball with an orifice to enable the chain to pass through, to suspend the lowest one.
I highly apreciate the efforts of the involved members in trying to figure out what this thing would be, and i feel much obliged for their kind cooperation.
My humble respects
Fernando
