Antique copper or bronze 1800s, Arts and Crafts vintage, Viking Revival door knob and matching escutcheon plates. This old architectural hardware has a design of scrolls, stylized dragon heads etc.
The doorknobs measure about 2 1/8" across and the plates measure 5 1/2" x 1 1/2". These have a lovely patina of age and some tarnish. There is still a old iron shank in the one door knob and we're selling these for restoration.
