No, I’m talking about the C-25 antenna loop control switch, not the local control knob that you have pictured.

 I assume you are talking about the ARC 7491 loop control?   At https://aafradio.org/garajmahal/ARC-5_loop_control_knobs.html you may find some possible ideas.  Having said that, for all the ARC designed receivers that have loop controls, I must admit that I have never seen a photo of one any being used in a WWII aircraft.  But for today's command set enthusiasts, of course!  Pretty neat capability!

I’m going to try to make the antenna control for the R-23-A/ARC-5 from scratch using junk parts. I’ll send pictures when completed.
