Polish ammo box?

[Endel]

Here is a unknown ammo box. The markings wz. reference to that is could be Polish. I glance over some of materials of captured artillery, there are nothing about wz. 15? Seems like one label is German one, not sure (frag gr. Patr. 23???). Second on is also unknown: luftmuna like a luftwaffen-munition or luftdicht?

Restenciled markings on the lid with white paint: 15 +++
Dimensions: 70 cm x 40 cm x 13 cm.

Maybe some Polish members here or anyone can help me to identity this markings over the box. I would be thankful.
