Hi I found this at a rummage sale in a box of odds and ends and thought it was pretty cool. Not sure what it is made of but thinking brass. It is non magnetic. Has some pretty interesting symbols all over it and has a place at the top that you could put something through it. It weighs 5 ounces and the size is 3.5x3.5 inches. It is a interesting piece. Any thoughts on what this may be. Thank you in advance.
