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. They are all made for about 1/4" square spindles.
One of these knobs has a little stress cracking near the stem on the back as shown in the last photo.
