3 pairs antique vtg fluted glass w/ brass shank doorknob door knobs spindles

Description

These are all very similar but each set does not math the rest 100% (as is common in a hunt for glass knobs). Each pair is matching to the other one on the same spindle and then I also have a slightly solarized knob in there as well. All knobs are architecturally usable. The glass is firm in the shank and the shank is firm to the spindle.
