Not to throw cold water on this, but I don't like the box! The rest looks good, but I'd like to see the cover of the case.
It is not at all like the several that I have seen nor the one that I have. They were/are all white, not brownish like this box.
I also have a box for the Kriegsvderdienst Kreus mit Schwerten and it is also white.
Seems like my bomber Nahkampf spange is also white, but not sure.
