Nice addition Geoff. As mentioned if you could afford to buy one I guess it would be allowed. Doubt you'll ever see this type of armor being worn in a period photo. I believe it would be worn underneath tunic/uniform. Be great to get full translation of label, charm pocket kanji & hand written kanji. I don't think this armor would be effective against US ammo but more a psychological type of protection. Might have its benefits against shrapnel.
