I found those other crates during my years long search for a rifle or LMG ammo crate. I got this one from a fellow forum member. It’s missing the top but still has the original screws for the top. One thing that is really cool is the small remnant of a label that has the Tokyo First Arsenal star stuck in the pitch that was used to seal the crate. I’m pretty sure it once contained 56 boxes of LMG ball ammo like these two. Again, the translation is courtesy of Edokko!
