  • The "Motor Dictograph" is a system for closed-cabin driver/passenger communication and was first displayed in the 1917 Salon and Shows.

    It comprises a carbon microphone built into the passenger cabin, and a horn speaker which is mounted near the driver seat.

    The horn has a height of 10"; the typeplate on its base reads 6 Volt - 2 Amp.

     

    It was still in use in 1925, when a Minerva AF was equipped with the system.
