When I go out hunting treasures, I never quite know what I will bring home. This old iron metal lock set is a perfect example. The enameled door knobs are in good condition (though one has a small patch of white paint on it.) One door knob is brown and the other is black. I do not have a key. The lock itself measures 4 1/8th inches tall by 3 3/8ths inches inches wide. It is in good condition with little if any rust. The lockset is marked, NORWALK LOCK CO.
