lot old antique white porcelain doorknobs, vintage architectural hardware

Collection of eight early 1900s porcelain door knobs - three sets on iron mounting shanks, and two single doorknobs. The door knobs measure about 2 1/8" across, 1 3/4" to 2" deep. The spindles measure 5 1/2" and 6" long.

All of these have been used, and show wear, crazing and discoloration, and soil / paint marks. Sounds worse than it looks, these are good old original pieces, far nicer than the newer reproductions!
