Winner: RH - Regarding your mystery wiretapping device, it is a Western Electric
model 300ABC telephone line recording unit. Western Electric was the
manufacturing company of AT&T up until the mid-90s, and furnished a
lot of kit for the military. Based on the design and housing of this
unit, it was likely manufactured some time between 1939 and 1946. While
this could be used for wiretapping, these devices were common in
military command posts were it would be used to record phone
conversations between officers, and the recording would subsequently be
transcribed and filed.
(Additional insights welcome.)
