Here's a set of four Philco hex knobs pulled from a Philco 29X on the auction site:

The price is ridiculous, but this will clearly illustrate what you need. They will be much cheaper from Mike, Julie, Kelton, or Dave.

Ron;
  Another reason not to buy from this guy, aside from his Walton Brand Z knob style pricing, at least for a non U.S resident and I quote:


We DO NOT ship international packages as gifts or mark them as -0- value. Period.

 Great, then I will never bid on or buy anything from you, PERIOD, if your misguided sensibilities won't allow you to accommodate a non U.S buyer in purchasing your overpriced merchandise. The U.S government doesn't care whether the Canadian, Australian, British, or Northern Rhodesian government don't get their cut, why should you?
