It would appear that the feedback winding is open which will render the local oscillator inoperable. It's the small winding on the outside of the oscillator coil. Remove that winding, insulator, and discard replace insulator with a replica made from thin plastic. Rewinding requires 38 or 36g wire at about 14t. You can run a needled over the existing winding and count the bumps to ascertain the correct number. Direction is important. Wind it the wrong way around and won't oscillate.
Before you pull the trigger do check the wires going from the winding to the terminals that they go to that winding that is suspect. Since the diagram doesn't list the pin connections vs what winding. I can't make a absolute answer that coil is open but there's a real good chance.

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.
