Authentic antique and vintage architectural brass door knob lot... a ssorted large and small, worn with a patina of age and wear
These range from about 2" to 2 1/4" across and most of them are made for 1/4" square threaded spindles. Four have unthreaded spindle sockets, two are 1/4" square, and two are about 3/8" square.
A couple of the set screws on smaller knobs are badly and a few have stress cracks.
