I’ve tried doing a valve search, a label search, a backwards photo search but I can’t find any details. Thanks in advance. Ethan

I can't yet tell the brand but it looks like a radio made for carrying one of several brands. What I can say is that it is a battery model so do not try connecting it to the mains or it will go bang, very loudly. It is also a 1940 model, as indicated by the letter G on the ARTS&P sticker.

Many thanks. Everything helps.

Complete valve lineup would help.
What I can see in the images, around 1947.

Definitely 1940, also going by the -G version (long bulb) of the 1N5G.
Not a small volume maker.
Not AWA, Philips, Astor, HMV or STC.
My first guess is Healing.
Valve lineup is:

1N5G(T) RF amp
1A7G(T) Mixer
1N5G IF amp
1H5GT Det & 1st audio amp
1Q5GT Audio OP

Looks like it has provision for a mains adaptor but a radio like this will run for hundreds of hours from 10 x alkaline 216s snapped together and a couple of alkaline D cells. It should be a reasonable performer too.

Connect the correct batteries to the right wires and it will probably work.

I have a number of similar radios in my collection.

I think it is close to a Healing 500b or 501b. Here:

The model number will start with 5 (no. of valves) and end in b (battery)

A lot of Australian brands did not start using new on the market valves sometimes 10 or even 20 years after introduction.
So hard to determine from that data.
However this likely lineup indicates Airzone model 457 made in 1940 or very similar.

The 1.4V battery Octal valves appeared around 1938 so this radio was reasonably up to date.
Post WW2 they were obsolete, replaced by the all-glass 7 pin series.
I'd ruled out Airzone because of the chassis plating colour. Although I don't have a schematic for the 457, as I recall, it has no RF stage, 2 x IFs and a 2 gang tuning cap.
The Healing 500b looks very close, except no external power connector.
The 501b has this but it's an octal plug.
Because of the 1Q5 the external DC on the filament supply would have to be 1.5V unlike the series filament 501b.
Close, but not identical.
Circuits for these things were pretty much the same anyway.
It's most likely to be a Healing because of those unusual 180kHz IF transformers that Healing were fond of. The low IF gave the radios bags of sensitivity and selectivity.
Stromberg Carlson made a set with the same valve lineup but the chassis was longer.

Oh, Ethan, have you worked on battery valve radios before? If not, you need to know the valve filaments are easily destroyed if you connect batteries up incorrectly or make a slip with a meter probe. Precautions are necessary!

Is that a mechanical ON/OFF indicator in the dial, above the middle knob?

Looks like it, I think. It says ON in the photo. The knobs say VOLUME on the left, unable to read the middle knob but it must be the TUNING, while the right-hand knob says SWITCH (I guess it's the power switch).

The knobs are like those used by STC around that time. However those of my STC 632 have a concave centre wheras those of this radio appear to be convex. Whatever that might mean; did STC make radios for department store name brands?
