> the number of turns and direction of those turns more important than the finished coil resistance?
Yes. The resistance is rather unimportant. What is important is the inductance, but not so much on this particular application. The the secondary is very important as it and the tuning cap determine the oscillator frequency. The primary (what you are rewinding) provides feedback from the cathode to the control grid causing the tube to oscillate. It doesn't have much to do will the frequency that the oscillator is operating at.

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.

Now I think I've got it!
