Thanks Terry for the info on the Philco P-429.
The chassis is the same as the BP413, the valves and transformers are all mounted in the same places above and below the chassis. It looks like the valves in the P-429 are Mazda Octal with 1.5v heater voltage, but the circuit seems to be basically the same as BP413 apart from the bandswitch. I'm sure that I can use this manual to help identify the values of some of the components that need replacing. See photo of underside of the chassis.
Very strange how there doesn't seem to be a manual listed for the BP413 anywhere. Maybe it was a 'special order' for the British Army, the valves used are all British Army type valves similar to those used in the R109 receiver and WS38 set.
