Price:
$12.00
These knobs are a dark maroon color, just like some originals I have. As of now, this is the only color available. Knobs "C" and "D" are the front fine-tuning knobs. Some models used the smaller knob "C", some used the larger knob "D". Knobs "C" and "D" fit different size shafts.
Dimensions:
Knob "A" is 1-1/4" diameter, with a 1/4" x 3/16" hole. (oblong)
Knob "B" is 1-1/4" diameter, with a 1/4" serrated hole.
Knob "C" is 3/4" diameter, with a 3/16" serrated hole.
Knob "D" is 7/8" diameter at the base, with a 1/4" serrated hole.
