Who Makes the CT83F Quadrant?

I've managed to lose one of the anodized knobs on my CT83F control quadrant and would like to buy another, but I can't figure out who actually makes these things. Anyone know?

I'm pretty sure Dayton Murdock manufactures those.
You can search the forums here for him.

You can also contact Blake or Vince at Flyboy Accessories.
