In excellent condition what must have been a very uncomfortable to wear military lip mike manufactured in 1943. Designed to be used with most available US radio sets, the microphone is worn close to the operator’s mouth as seen in the photo and responds to his voice. However sounds originating farther away, such as background noise or battle noise, are cancelled out. All the straps, ear loops and wiring are in good order. All items are sent tracked usually by Royal Mail.
