Lion door knocker / bronze door hammer

I am selling a very beautiful door knocker for the entrance door, sometimes called a door hammer. It features a lion with a ring in its mouth. This is an authentic vintage item and not a reproduced product in a vintage style. There is a signature on the back "PCCF". Here are the total dimensions: width 12 cm, height 20 cm, depth 6 cm. The lion's head measures 13 x 12 cm and the ring has a diameter of 10 cm. The weight is: 865g.
