Knobs for Collins 51S-1 receiver
 

Looking for a main tuning knob and a band selector knob for Collins
51S-1 receiver. Main tuning knob should have round opening.

Will pay cash, or, if interested, I do have for trade parts from 75S-1
receiver: small knobs, 70K-2 PTO, dial assembly, power transformer,
audio transformer, 100 KHz crystal, and other parts.
Please reply directly to

Thanks,
