Would anyone perchance have a circuit for above?

Here is a copy of the circuit from the 1938 Mingays Radio Trade Annual.

Thanks guys: I can now trace where the stray wires belong (owner attempted repair & got lost). The pain is I see a broken coil wire. So after the food forage & trip through the medical system, I will attempt a coil repair (has to come out). Green is ominous.

The circuit is exactly the same as my Airzone 545. Only diffence is the 6C6 is a 77 and the 6D6 is a 78. Apparently there is common fault on this type of 6F7 oscillator on the Airzones. The secondary of the local osc coil goes open circuit. I and am trying to rewind it and get it back on frequency. If you are looking for C1 & C2 they are inside the osc coil former.
