Your welcome
The resistance isn't that important although 650 ohms a foot sounds very high for #38g. That winding is just for the coupling of the rf signal to the input grid of the mixer tube. It isn't in a frequency determining circuit. That would be the secondary of the coil.
I was a bit surprised to see that you had hv on grid 2 of the mixer tube (good), I was thinking that the oscillator wasn't operating. But it seems to be working ok.
Glad to help out when I can.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
