Up for bids we have what I was told is a WW2 Japanese Civil Defense Helmet. I originally listed it thinking it was a WW1 Doughboy Helmet but was informed by a more knowledgeable person as to what it was. Stamped 2800 under the brim. Metal shell only, no lining. Questions or comments are welcome. I will be out of town when this auction ends. That may delay transaction for a day or two. Thanks for looking.
