[GreenKeys] 33 TWX volume knob

[Wayne Durkee]

Keith,

The knob has a metal insert that goes into the slot on the volume stem, but you could fabricate that yourself if you are handy with metal.

You can purchase color dyes from these folks as well so you can make the part any color you wish.  If you are patient, your copy will be indistinguishable from the original - no kidding.

I don't know if there were different sized shafts over the years, but mine is 1/8" in diameter.  In lieu of an actual knob, could someone take a picture of one so that I could try to find a modern part that's as similar as possible?
