45 EXCEPTIONALLY EARLY GERMAN CARBON MICROPHONE WITH WOODEN DIAPHRAGM:(37KB)
50 WESTERN ELECTRIC CARBON MICROPHONE Circa 1920s. (27KB) Early microphones such as this were mounted in springs to isolate them from local vibration. This microphone is mounted in a special stand which is similar in design to the stand used to support Western Electric loudspeakers. Unlike the loudspeaker stand, however, it has no holes through the rim and a few other details of the casting are different.

102 UNIVERSAL MODEL BB MICROPHONE:(9KB) This microphone consists of an Universal Model BB double-button carbon microphone mounted in an Universal Desk Stand. The stand is equipped with covers which can hide the microphone element from view. During the early days of broadcasting many singers and performers were terrified by the sight of the microphone and it was often hidden behind a cover like this one or even hidden from view by a piece of silk material draped over the microphone. This is the same microphone model which was used in the original ''Wizard of Oz'' movie.
