Does anyone recognise who manufactured this chassis?
There is no brand name anywhere on the radio, other than on the Magnavox model 1500 speaker.
There is however 2 cosmetic features of the chassis that I'm hoping one of you experienced collectors/repairmen may have come across before, and can recognise as being used by a particular manufacturer.

The first is the transfers used on the back of the chassis, one being the "danger" warning, and the other, the complete word "earth".
I guess the paint colour could also offer a clue?

The second is a black ink stamp on the side panel, on the inside of the chassis. This is mostly illegible, but I think the second line of script may say "Australia", and the forth line "1st test", and the last "LGB (?) and test".
There is also the number 411 written across the stamp in pencil, but I assume this is for employee identification rather than the radios model number.

I also thought I'd include a view of the underside of the chassis, incase someone recognises the design &/or components used as common for a certain maker.

BTW: Once the images above are in view, you can click on it to enlarge it slightly.

The valves used in this one are No's 80, 42, 57, 6C6, and an as yet unidentified valve, which I'll show you while I'm at it lol.

As always, any help will be greatly appreciated..

Transformer looks a little like what I would expect in an EMMCO.

That chassis I worked on proved to be an AC5. It had no meaningfull ID.

Did a cross reference with the valve lineup and both HSRA and HWS websites pages of radio brands and models, they have the model, year and valve lineup that was used and came up with nothing I'm afraid. It sort of looks abit like an Airzone I have, a 1935 552 tombstone. My Airzone also has a magnavox speaker. Hope this narrows it down abit.

I note that Airzone was Airzone 1931.

I have some suspicion that EMMCO were involved with Airzone. The tuner looks more like the "Stromberg Carlson" one that everyman & the dog tended to use.

RCS made bits for hobby, & commercial stuff. The last Airzone console (Battery) I fixed had an Airzone branded speaker in it (permag). Which is why I made a concerted effort to fix it.

Slades also made unbranded radio's. I did have one production "brand name" radio that was branded one model & had half of the previous models bits in it. Brief amount of head scratching, until I clicked onto what they had done.

Many models sold as "House brands" were also made by ?, making it almost impossible to get a circuit, without reverse engineering it.....which I have done.
