This is a vintage solid brass Lion Head cameo oval door knocker. It is not marked, but I believe it was made in England. The knocker is 5 1/2" x 3 1/4" x 1 1/8." It is in excellent condition with a few spots of tarnish. It weighs 546 g. There are two threaded holes in the back for attaching to your door, and it comes complete with two long screws for that purpose. MBR.
