• Modelo: Loud Speaking Telephone - Western Electric Company Inc.;

• Anotaciones
• At the 1912 Boston Electric show a number of these Western Electric Loud Speaking Telephones were used to demonstrate their use as announcers - to announce interesting events, to page visitors to the show, and to furnish music from a phonograph in the transmitting booth. Groups of people gathered around, listening open-mouthed to the voices or the music, seemingly coming from nowhere. Even a child which was separated from its parents was found through their agency, exhibition officials were summoned to their offices by means of these instruments.
  Straight neck horn, wall hanging.
