Part 3 and last.

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.

I would agree. The date of the radio is 1920s and it's a TRF radio.

As you say the variable caps line up with the dials (I've looked at other
pics on the net as well). Perhaps band spread and fine tuning? (I'm way out
of my league here, just a guess).
