Hi folks, After many years I noticed that my dad's K1 does not have the original tuning knob. It also does not have the NB module. So, I wanted to ask kindly if anyone would have for sale please: KN1 large knob, diameter 1.25", shaft 0.25"; Rogan #RB-67-3-M p/n: E980021 KNB1 noise blanker module (built / unbuilt)? Thanks a lot, 73 - Petr, OK1RP
