huge old antique pulley, blacksmith hand forged iron w/ hook, worn weathered wood

Very large, very heavy forged iron and wood pulley out of an estate here in Wisconsin. This might have been a farm / barn pulley for moving hay or equipment, or may have been used for hauling goods or equipment on a boat - I just don't know. It's sturdy yet though the wood is very weathered. It would work wonderfully as a hanger for a light or something like that.
