Capehart-Farnsworth Knobs needed

[kbmuri]

There's an off-sound-on knob in eBay 130198549885. 2nd photo, dead center is a large gold knob. The Capehart knob is just to the right of it and partially on top of it. I don't see the matching tuner knob, but it's a start, and maybe it could give your mock-up guys something to work off of. It looks like there are some other knobs that wouldn't be "correct" but might look presentable, for the two smaller knobs. If that helps.
