I¡¯ll see if I can find it.
An internet search, as expected, turned up mostly things that weren¡¯t even knobs.

Some years ago, Sherwood Engineering listed the concentric RF/AF knobs in its catalog as an upgrade.? Rob Sherwood might be able to provide the name of the manufacturer and the part numbers for them.?

I'm not sure.? I bought the set at a hamfest and it had the knobs on it already.
I'm not one for making "mods" to vintage equipment but this one is really, really nice and is easily reversible.
Trying to find anything on the internet today is such a death march that I'm afraid that I'll leave it to you.? The type of knob used on 4-Line is called a "bar knob".? I'll try searching but I'm sure I will get 10 pages of "Buy it here" rubbish...
My patience with the internet is thinner than rice paper at this point.? It has been ruined.

Hello Steve,
Is the control you used still available or is it obsolete? Thanks

I just took a quick look inside my late (28xxx) R-4C and it looks like there are circuits and structures that would interfere with a shield extension but I can hear the modulation a lot more when the slug/rod is out the back.
My receiver is totally stock except for having changed out the original AFG/RFG controls for a nice concentric plastic knob set that looks just like what Drake ¡°should have¡± put there.
I will likely leave things as they are, as it¡¯s more of a collector piece that I play with. ?It¡¯s similar in the auto world as a stock vs modified ¡°thing¡±. ?I am also not short on things that I need to do.
