A a bit more background research on this radio while I wait to be able to continue work (more pics later).
I am now practically certain that the manufacturer was Gilfillan. Comparison with other models by this manufacturer (Thanks Google images) reveals one or two details in common. Not the least of which were the list of patents decal, the use of unterminated wires for the antenna and ground connections, and the particular tube shields that match the shouldered shape of the components. Also type and style of capacitors.
Some probing around yesterday indicated there was little, if anything amiss with the converter tube components (replaced osc grid resistor). Voltages appear to be correct within reason. Cleaning the bandswitch improved band B, and WWV on 5 MHz is coming in stronger. Band C still seems poor, but perhaps that is how it is. Need to test on the long wire again. I've ordered a replacement 6A8 converter anyway, since I like to have spares.
Cheers

I don't hold with furniture that talks.
