I was given these by our local tip lady who collects anything Bakelite for me.
They are a pair of phones that looks like when one hand piece is picked up the other phone buzzes.
Has anyone seen these before and is there a wiring diagram around.
I could nut it out but diagram would be nice.
I would also say you could speak and listen as well.
They are brown mottled Bakelite

I think these are a bit better engineered than a toy. All those wires and terminal strips would be similar to what goes in the real thing. Perhaps this is an office intercom...

Marge!! I have an important meeting in half an hour... Tea and Iced Vovos for three please.

I agree that they appear to be a level above toy. Probably used for short distance room to room communication at home (home to garage, etc). My guess is that it's common battery operation with one pair being for power and the other for the voice circuit.

Tracing out the circuit is probably your best bet.

They are half size compared to a standard Bakelite phone

I found the info guys, they Chad Valley toy telephones from the 1930’s
English made and the company is still going.
Look up Chad Valley toys in Google

The box for your particular model states "For home and office use", so definitely considered a level above toy:

Where's the battery go?

In line, usually placed at one end or the other. Typically would use two of these in series:

Yes they are Chad Valley toy telephones from the 1930s and they were intended to be used as toys. There were several versions of them over the years and each successive version was made more cheaply than the last.

Yours were actually made by GEC (England) which was a major manufacturer of telephones for the British GPO, the Australian PMG and other countries so they were much better made than the later versions which were flimsy black plastic. I have seen a few of the later plastic versions in antique/collectable shops but they were all damaged. Yours look to be in good nick and the mottled brown bakelite is nice

These phones used a 3V battery and the installation instructions are available at: http://britishtelephones.com/chadvall.htm

Way better constructed that the usual 'toy' phones I've ever come across, and given the separate circuits for power and speech I'd say they would have made pretty reasonable short run links for upstairs/downstairs, house/garage, etc, the carbon mics notwithstanding. The quality of the documentation is also way above what I'd expect for toys.

That said, as a kid I would have loved to hook a pair up between my house and my mate's next door.

If they are still functional, it would be interesting to know how they perform in use.
