News Flash! It turns out the set was retuned to the Birmingham transmitter.
The RF tuning cols have less turns than are required for 45Mc/s and the tuning cores are metal. Also, the big giveaway to confirm that the set is tuned to channel B4 is that local oscillator tuning capacitor has been changed from 40pF to 22pF. The local oscillator will be tuned to 53.75Mc/s instead of 37Mcs.
