This helmet is missing from the main references on the topic. It always had me baffled because of the snap on the top. I always wondered if it the inside of a "Bone Dome" and the snap fastened it to the outer shell. About 10 years after I found the helmet, I found the light. It appears the light would snap to the top in case the crew needed to ditch into the ocean; I have a navy skull cap with the same feature ..... I now believe the helmet is a Canadian coastal command helmet.
