The Dymo tape is interesting....someone was trying to work out something.

A list of the valves may help identify. The fact it has metal valves suggests after 1936 and one valve in sight may need changing back to metal.

I see nothing yet in the photo's that suggests external power supply.

This would cause me to think that it is likely a "highly dangerous" AC/ DC model.

It may have a model number on it?

More info........... Photo of the inside of the pan may also give clues. eg heavy wattage "dropping" resitors.

If you want to restore dial, a signwriter / graphic artist may be the go. Or it could possibly be scanned & re-printed with a paint printer.

Try using this link to identify your chassis

That chassis looks home made by the wiring, I've never seen yellow/green earth wire in a commercial set before

It could also be a case of whoever did it was not terribly fussed as to what they used & scrounged the wire from mains cables & whatever.

I have seen plenty of examples of it.

There is something similar in Siliconchip archives which might help

http://www.siliconchip.com.au/cms/A_112076/article.html

1938 612 battery, 2V for heaters, 3 x 45v for HT.

Not 6v as yours is (metal valves) but has the same dial. Different cabinet. It has a permag speaker which is also suggested by the 6mm socket at the back of yours.
So maybe external power supply fed in through the other socket.

Know the ins & outs of that one. I fixed it..

That one is a battery set which had flying leads to the batteries.

The terminals suggest yes but I would not dare fire that thing up without going through it with a "tooth pick ,comb & circuit" to find out what has been done to it and if it is wrong. Often sets are abondoned because of a fault or stuff up. You need to look to find out which one it was.

This I did with the one featured in SC and I was horrified by what I found. It was several stuffups. The first was by whoever touched it & thought they could fix whatever was originally wrong: Then added to it & killed a valve.

No attempt was made to fire up the set prior to inspection nor after until the mistakes were rectified in conjunction with replacing caps & any dud resistors & wiring found during that process.

The SC one has 2V filament tubes eg. 1K7. List the valves & we may be able to find out what yours is. 6V car batteries were common when it was built.

Cloth covered wire is easily aquired to replace the plastic.

That set was in fantasic original condition for its age. Restoration of the cabinet would be criminal.

Note: Current HRSA Radio Waves there is a guy reproducing dials.
