antique white ironstone porcelain and brass door knobs with matching china cover plates

Pair of antique vintage architectural, white ironstone porcelain doorknobs with solid brass shanks and matching ironstone porcelain cover plates. These are the original vintage doorknobs and plates and not reproductions. This set of door knobs measure 2 1/8" across, 2" high and 1/2" across the brass doorknob shank. The steel connecting shank measures 0.3" square. The white porcelain cover plates measure 2 1/8" across and 3/4" high with brass inserts for the doorknob shank.

These are in excellent condition with a lovely patina of age to the brass. There is some flakes of old paint to the cover plates and they each have a discolored hairline gap from the center hole to the edge of the plate. Theses gaps were originally added by the manufacturer to allow the plates to change size from temperature expansion and contraction without breaking.
