german ammo box label id

[Mannlicher]

Hello everyone. I've recently found a wooden ammunition box, 75cm length, 41cm wide and 31cm deep, labeled as per the picture:

I recall seeing this type of label somewhere in the past, but searching info regarding what the box contained proved fruitless. I'm prety baffled right now and didn't knew where to turn for an answer. So guys, tell me what the 16 Flakz....Korper housed in this box were....

Eternally grateful.

If it says flakzunderkorper,it should be fuzes for anti-aircraft ammo,just a guess.....Pete.

I guess it should hold something larger, the box is kinda big and the label states it contained only 16 pieces weighting 250 grams a piece.

Thanks for the imput, still searching for the answer.
