The top part that mounts to the door hinges with the bottom. It is approximately 10.5" in length, 7" in width, and 1.5" in depth at the top and very bottom (and it's about 1" thick elsewhere).It is very heavy - weighing about 6-7 lbs. Found in northern italy near venice a few years ago. It appears to be made of brass - there is some tarnishing and wear consistent with age. This item is made of brass.
