Cool! Thanks for the info.! I was wondering if it was an ammo box. There is two of them. One still has the most of the contents on the list but they are not in the best shape, not sure what was in the other box originally but it is full of spent Japanese shells right now from larger caliber weapons. There was about 4 of the 30 round ammo strips close to the boxes when I was checking them out.Ammo box for Japanese Type 92 HMG. Holds the 30 round ammo strips in cardboard or cloth covered cardboard containers. It would normally have two thick leather straps as handles or shoulder straps for carrying, but it appears they have been cut off. Nice box!
