Configuration of German Aircraft gun belts

One of my collection sides of ammunition is German Aircraft gun ammo. I want to collect the belts too. Now it is not that difficult to get the links and shells, but to configure the correct belt .There are Brand, Spreng, Minen and AP(I) Shells. Does anyone have, or know about documentation or pictures how such belts were configured? Was it due to the mission? P.E., flighing air to air, attacking bombers, Air to ground, or even day and night.
As soon as i have the info, i’ll post the belts as a result on this forum.

Have something abouth the 7.9 Mauser.
