Very nice original helmet. From the research I've done this is a late war helmet made of some type of Alloy. It's still fairly heavy or I would have guessed some aluminum Alloy. But it's closer to a spelter or something. Original paint and liner. Liner is loose and not attached but is still there. There is kanji on the liner, but I can't read it and my phone wont translate it. Very cool helmet. Scratches on the top of the helmet Front being on the ground. If you have any questions please feel free to contact me at any time!
