Philco 42-390, code 121 speaker
#4

Using a 5W  1.5k  ceramic resistor in place of the field coil and using a 4 ohm PM speaker, I was able to bring the radio to life today.  If I cannot locate an original speaker, I will wind a FC for 1100 ohms. The resistor replacement cannot be a permanent solution.
