[Hallicrafters] HT-3X knobs

[Waldo Magnuson]

Hi Ed,
    I have two SX-100s on my bench.  The diameter of the mail tuning 
knob insert on one is 1 3/8 inch and on the other 13/16 inch.  
Depending on the time down the production line, knobs can be different 
even on the same model number.  My SX-111 and HT-37 boh have a 13/16 
in. dia. main tuning knob insert.

I really need is the metal insert for the large tuning knob. The rig is 
an HT-30, but I know the SX-100 uses the same size (1.367 inch) because 
that is my receiver. I think the HT-3# series of transmitters all use 
the same size as well. I would buy the whole knob if I need to, however.
