These door knob back plates are strong steel at the core but covered in bronze, allowing these gorgeous shades of patina to develop over the years. Very Victorian acanthus leaves and edge work.
Good used condition, some wear on the knobs and backplates, a little rust on the backside of the backplates, steel I assume, a slight coppery sheen in places.
Diameter of knobs: 2 1/8"
Projection of knobs: 2 1/4
Height of backplates: 6 1/2"
Width of backplates: 2"
