Eastlake antique brass door knobs, original patina art nouveau vintage hardware lot

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.
