Hi to all:
I am looking for a black vernier reduction control knob with a Dial Plate.  I believe the plate is screwed to the back of the knob.

I am going to use above indicator system with an air variable capacitor in a link antenna coupler.  Plate rotation for minimum to maximum capacitance is 180 degrees.

Thank you,
Chuck
