Aircraft Part Carter CE 87/AIC Boom Microphone Talk Close New

This item was purchased from an aviation surplus sale. I do not know the history of it. It appears to be a new replacement microphone for a headset of the same brand. This unit came in a large parts bag with several items of the same exact type and model number. I am splitting it up into individual units. It was tagged, "NE" with no aircraft type indicated. I am not able to test it. It only comes with what is shown in the pictures.
