vintage steel doughboy helmet.I am not sure what this helmet was used for. Civil defense? It is pretty cool looking, and appropriately 3/32 of an inch thick metal, with a reflective material on it that is about half worn off. Refer to photos. The leather strap and inners are in pretty good shape. I don’t have much knowledge of military helmets, but I am assuming this is not military. Still a nice display piece.
