Navy M-5A/UR

Introduced in the last year of the war, this is an adaptation of a Marine Corps set mike that originally hung over the operator's head and nestled against the skin between the lip and the nose - very uncomfortable to say the least. Because of its noise cancelling characteristics, someone got the bright idea of making it into a boom mike for the airdales. The Navy initially called the assembly only by the designation for the boom assembly, M-5/UR, primarily because it was only available for retrofitting to existing headsets. When the entire boom headset assembly became available, it was given the nomenclature H-46/UR. Below are the "retrofit" instructions from Airborne Radio Maintenance Notes dated November 1945. Note that it is aleady been modified to an "A" release configuration.
