Early 1900s antique door knobs with original brass plates and hardware - this has a lovely patina from age and use, and just a few traces of old paint. One knob is solid brass, one knob pressed glass with mercury silvered center. The brass door know is slightly smaller, about 2" in diameter.
The steel shank is a little wobbly, but this looks like a good usable set overall. You will need new screws, as we don't have the original screws for this, it's just the hardware shown.
