Nice job!
As a mental exercise I was looking over the diagram to see how I might solve the problem. The large coil "L1" needs to resonant at the bcb with a 350mmfd vari cap in parallel. Top tap to the bottom resonant to the police band. Bottom tap to bottom don't think particularly critical as it's used for coupling the antenna energy into the set. "L2" Just has to be resonant at the top band with the 350 mmfd tuning cap.
Although I could be way off base.
I recently got a capacitance/inductance meter and there are online calculators to sort frequency vs capacitance and inductance. On the other head I rarely buy mulit band sets missing loop ant. Life is short!

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 it!
