Very hard to find helmet for waist gunner. Certainly used on B-17 but not sure of other 4 engine bombers. This is the early model with the long, pointed ear flaps that were shortened rather quickly as they were too obstructive. This one is in unissued condition. Even though the helmet is metal they somehow applied a slight fuzzy surface. I would assume this fuzz is so that it wasn't too cold to the touch at high altitude (Maybe). At any rate, this fuzz has the weird ability to make almost any contact a mark. So the surface has some marks as per photos. Inside is minty/unissued. Very hard item to find.
