I really appreciate your reply. I have attached two more pics with the lettering. These three pos total is all that I have at the moment. I was never sure it was a bell or not, hence the posting. I pointed out the two lugs at the bottom to my brother, but he said maybe it was some sort of buoy bell that would be bolted to the buoy so it would ring with the movement of the waves. Maybe the letters stamped will shed some light.
