The MkII “Talker” helmet was developed in 1942 for naval personnel, allowing communications headgear to be easily worn under the helmet. It was a very large and somewhat ungainly helmet to wear though it did serve its purpose very well. It was designed to accommodate wearing headphones for Radiomen or anyone using shipboard sound-powered phones.
A great used helmet that been there!
Good condition – The color is more like the first picture
