Default Re: Vintage Arrow ( Toy? ) Telephones

Hello,
This is pure guesswork but I think what you call a relay may be a buzzer.
If you look carefully there are two thick metal prongs that stick out in each phone and where they meet the plastic case there appears to be a + and - sign cast into the plastic so presumably a battery or batteries fit in there possibly held in place by the piece of thick wire that goes across.
If this is correct you might have to use trial and error to determine the correct battery voltage.
Yours, Richard
