The Harvester Hay Trolley Unloader Barn Farm Pulley Antique Vintage cast iron

The Harvester Hay Trolley Unloader Barn Farm Pulley Antique Vintage cast iron. It appears that a chain was added to it and I did not know the purpose of that. All of the pulleys do turn. I don't believe it will swivel much because of the chain but it does swivel some until the chain prevents it from going any further.

It is not new and show signs of use and age. Please use the pictures to help determine the condition of this item. I don't see any cracks in the cast iron but this is not mean that none exists, it means I don't see any and that might very well mean that none exists. I have looked it over fairly thoroughly and I have not seen any cracks.

There is rust on it and I do not know what the original color was but it may have been gray and if it was much of that color is missing.
