Part 3 and last.

There are three large dials on the radio. The one in the centre is
labelled
"Wavelength", clearly for tuning the desired frequency. The other two are
not marked at all. What do they do?

Buck,
Without looking at a schematic, I would guess all three dials are
for tuning the RF stages, as in an A****er Kent model 20. I don't
know the date of your radio, but the AK 20 preceded ganged tuning
systems. The interior photo seems to locate the tuning condensers
approximately where those dials are on the front panel. Later radios
used metal bands or even chains to link the three condensers, and
then we ended up with three condensers on one shaft.
But I'd be happy to be corrected.
Cheers,
Nelson
