Unfortunately it's the only picture I have, my sister in law is trying to figure it out. Not sure if there are any more pictures, I will ask. It's one solid piece, there is a hook at the top. Around the middle of the ball there are 3 rivets, with a hole above each rivet. ( one can be seen in the picture). There are no markings on it. We have been guessing a counter weight. Also people have made the comment of possibly being a bell clapper.
