    Need Help!! Identifying military receiver switch possibly ww2 era?

    Hi all, I am looking for help identifying this piece of a communications receiver, possibly ww2 era?
    It is cast from aluminum, and you can see where there would have been a switch arm pivot to select between 'voice' and 'tone' as seen marked on the casting. The only other marking is the word 'receive'.
    My thoughts lean towards it being part of a field radio or telephone as there are slots to possibly thread through a belt or shoulder strap. As it is incomplete it is difficult to identify, so if anyone has any idea of what it is, where it was from and where it was used that would be great. Any information at all would be helpful or anywhere I might be able to find a solution. All the best :-) https://ibb.co/hx1E0e https://ibb.co/fnc9Yz https://ibb.co/gNJu0e https://ibb.co/k7q7Le

    I can not tell you what it is, but it is definitely not a ww2 radio part (a radio switch would be about 100 times smaller). It seems to be designed to switch sound waves (voice or tone) directly into a pipe mounted transversely on the end. Which medium was contained in the system I can only guess at, perhaps it was part of some sort of underwater communication system.

    regards,

      Thanks for this response, it certainly makes sense what you are saying.
      Assuming the device was still for communication purposes, what sort of application would involve the use of pipes to carry the sound? Other than the old technology of speaking tubes, I thought the carriage of sound would be purely electronic.
      It has the word receive marked in the casting, does this mean the pipes would be carrying sound TO the device, which then is translated into another device i.e amplifier.
      Would you think it could have been used in naval applications on a ship perhaps?


      Sorry for all the questions but this really has got me baffled!
