This is a heavy solid brass spring hinge. The hinge is meant to be mounted on the front of the door in order to keep the door closed. (The spring faces outward.) The spring is strong and will handle a heavy door.
The hinge measures only 1 3/4 inches vertically and 1 1/4 inches across. It has a patented date of Oct. 27, 18– stamped on the wing. The year is punched out by one of the holes.
We will include brass screws with this unusual and hard to find hinge.
