Does anyone recognise the Band III converter on the back of this set?

I'm assuming that as the set is a TRF, that this will be one that outputs on the AP frequency...

It's the Stirling converter. My Pye LV30C was equipped with one. The LV30 is a TRF receiver so an add on converter was the only method possible to receive Band3 transmissions. As for my LV30C the B3 converter was fitted inside the cabinet and the power supplies for it were scavenged from the main receiver.
Versions of the Stirling converter were made which had an internal power supply making it an independent unit. No alterations to the band 1 only receiver required whatsoever.

Yes that's one, we had one on our HMV TV for the opening of the Winter Hill transmitter on Channel 9, in, I think it was 1956.
Very useful item, nice box and PSU to build other items with it after they became redundant for channel conversion.
