Am looking to buy one (1) main tuning knob to complete an NC-183
restoration. This is the 2-5/64 inch diameter black plastic knob with the
polished chrome-like insert. Would be equally interested in finding just the
chrome-like insert although I have a feeling if someone has one, they'll
have the other.

Thanks to the vintage gear community for the consistent support keeping
these grand old dames on stage.
