There's actually not a lot of primary sources on the reticles used in German armour.

So developers of some of these WWII "realistc" shooters have to design new ones.

I would guess there's better documentation of mines and bombs.

I've actually wondered about that too! My uncle has a bunch of old rifle optics equipment. Very unusual reticles on some of them!
