lot antique black & white porcelain door knobs, vintage hardware

Lot of 16 antique black and white glass or porcelain door knobs (also one brown marbled door knob), with the old iron spindle hardware. All of these have been used, and show wear (some with crazing and discoloration), soil and paint marks, etc..

Some of these could probably be restored to working condition, others would be great for primitive coat pegs and clothes hangers, etc..
