lot of antique arts and crafts vintage solid brass/bronze door knobs, vintage architectural salvage

Collection of seven old antique heavy solid brass and bronze Arts and Crafts doorknobs. These are original architectural salvage doorknobs and not new reproductions. These door knobs measure about 2 1/4" across and 2" high. There is a pair of matching red brass or bronze door knobs. Three of the other knobs match these in design (but are a yellow brass) and two are a slightly different style.

These are in excellent condition with a lovely patina of age.
