1914 Magnavox Anti-Noise Desk Set, Type B1

1914 Magnavox Anti-Noise Desk Set This telephone was designed so that the users voice vibrated the diaphragm through holes in the top of the transmitter housing while speaking directly into the mouthpiece. Any unwanted loud noise entered the transmitter housing both from the holes on top and underneath the diaphragm thus canceling itself out. This desk set was found by the present owner in a Tandy Leather shop in Grants Pass, Oregon.
