>The original OSC. wire measures most like 32AWG by my mic, .02 off. The way it is coupled back to the det coil may have something to with it, parallel.
Ok the next way to re it would be to rewind it so that windings match the holes in the form. If you are sure abt the gauge of the wire. A gdo can be handy for roughly reading the resonant frequency. Or a regenerative receiver, if you put the coil near the coil in the regen rx at it's resonant frequency the regen det will have a null (dead spot)
Retuning the IF to a different frequency so the osc will track is a bad idea. The transformers are designed to have a certain selectivity curve and Q @ 260kc. Above and below this frequency not so much. There is a few more reason too.

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!
