Authentic early century assorted doorknobs lot... six brass door knobs, all nice architectural art elements in the Eastlake, Art Nouveau, aesthetic Movement, and Craftsman traditions.
They all have a beautiful patina of age and tarnish, traces of old paint etc. and they are about 2 1/8" to 2 1/4" across.
These are all made for about 1/4" square spindles and one of these knobs has an old set screw rusted in place as shown.
