Edmonstone Company Anders Push-Button Desk Set

The Anders push-button desk set has an adjustable transmitter that moves forward and back with the help of thumb screws. The receiver has a button on the back side and hooks right to the face of the transmitter. There are 10 peg holes (missing the peg) around the base. Extremely rare and beautiful desk set. Please see the scans of an original article about the Edmonstone Anders "Intercommunicating Desk Stand" from a 1903 The Telephone Magazine.
