GE Bakelite Radio Knobs 1930s -- Black / 3 Pieces

Note: One of the screws is missing from the knobs, and there is a small chip on the bottom of the same knob missing the screw.

My items are sold as found after being in storage for ~40 years, originally they were contents of a repair shop. I do not attempt to clean/restore the parts prior to selling, only a simple dust removal.
