[ForSale-Swap] National Knob needed. . . . .

[K9ze at aol.com]

 In the middle of a restoration of my Stepfather's 1939 National NC-101X 
receiver, and am in need of the bandswitching knob.
It's a heavily knurled black knob about 3-3/8" in diameter, and almost 1" 
thick.  The tuning knob on this receiver is identical, but is mounted on a skirt. 
 
Very interested in finding this knob, with or without a skirt - - - or 
something very similar.

Thanks for any consideration.
