British/Canadian Headphones and Microphone in cardboard-box

Original WWII British/Canadian headphones and microphone set in its original cardboard box, ZA-2905. The set is in unused condition. The microphone’s rubber mouthpiece is in good condition, somewhat dry as a result of long storage, complete set. Comes with its original plug. Used by tank crews and radio operators. We recently discovered a crate dated 1944 that still contains the headphones.
