While looking thru the early pages of this thread, I think this cap and coil
 is to form a series resonant circuit to make for a low impedance at the set's RF upper midpoint frequency, around 1200KHz. So that the chassis looks like a good RF ground plane without having to use a cap too large that it produces too much of a shock hazard to the set's user. With the 0.022uF cap, it needs a 0.8uH coil and that will yield about 6 ohms of reactance. Using the coil inductance calculator at http://www.66pacific.com/calculators/coil_calc.aspx and guessing 3/4 inch diameter and 1/2 inch length, I get about the 0.8uH value and thus the 1200KHz resonant frequency. Not completely sure that this is why they did this.

  A little sanding and re-spray took care of that. Here it is with a dry run of the dial face.  I picked up a reproduction back from Retro-Tronics in basic black. I could have payed a few more $ for a white one, but decided to just paint it myself.   Unfortunately, I'm missing the clips. Here are some clips from another radio. Does anyone have some to spare or have any idea how to attach it ? For now I'll just wedge a little foam in a few places to hold it on.   Finally, here's the new decal.
