this was found at Coral Castle in Homestead Fl. the builder of the castle was rumored to have dabbled with radio in the 1940's and gotten a hold of some WW2 surplus from the nearby base. i'm working with them to ID the items Ed (the castle's builder) owned.

any clues as to what it came from?

I think I have a couple Motorola TV's that have that sort of knob. May just be a style knob that was common then.

General Radio instrument knob from the mid- to late 1920s.

If procured in the 1940s, it was probably from a box of miscellaneous parts.

not quite exactly a match to the general instrument knob (ridge on top edge is thicker on mine) but close enough to get me in the ballpark.

It looks like it has two set screws and a metal center. Most likely military use over civilian use.

that's were i was leaning initially. wasn't the 2 set screw thing something common to WW2 gear and later found to be more prone to working loose than single set screw knobs?

I hadn't heard of that before, but it's possible. About the metal center, I heard that they added that not only for durability but also because if the plastic broke, there would still be something left of the knob that could be turned.
