antique white porcelain or milk glass doorknobs, vintage architectural hardware lot door knobs

Lot of old white porcelain or milk glass doorknobs showing considerable age and wear. These are right out of a barn - and before that, a farmhouse - here in rural Wisconsin. The whole lot is shown in the first photo.

They're all as found, and will need some work if you're wanting to use these on doors or anything besides repurposing with a primitive look. Some have discolored crazing or crackling, and all of the iron hardware is rusty.
