Pair of Glass 12-point Mercury Center Door Knobs door knob set with spindle vintage 1920s

This set is ready to install with a simple screwdriver. Both knobs are super sparkly and bright silvered glass. Removed from my old house in the 1980s and hasn't been used since. Not compatible with standard modern door sets. Great for interior doors with the right hardware. The spindle (connecting bar), screws, and knobs are all in great condition for their age.
