Huge lot of about 22 assorted antique and vintage white porcelain doorknobs for restoration . There are about 22 door knobs and most of them measure about 2 1/8" across and 2" high (over the metal shank). The doorknob shanks are made for 1/4" square spindles.

There are also a couple of old escutcheon medallions and an old rim lock (for parts).

These have wear, rust and old paint. A number of doorknobs have old hairline cracks to the porcelain.
