What you are looking for is a coil that =1.145mh if the total capacitance in parallel with the coil (fixed and trimmer) = 100mmfd. This combination will yield a resonant frequency of 470kc. If you reduce the inductance or capacitance the resonant frequency goes up. Conversely if you add inductance or capacitance the resonant frequency goes down.

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.

Now I think I've got!
