A Vintage Small Brass Sealyham Terrier Dog Design Door Knocker. It measures approx. 2 1/4 inches long including back mounting plate and approx. 1 3/4 inches across widest place of dog knocker piece. It has 2 pre drilled holes so is easy to screw into place (no screws supplied). Due to its age and construction there is some sideways movement to the hinged knocker piece however still works as it should. The photos might show the brass colouring to be lighter/darker or to be a different shade due to the light conditions when the photos were taken.
