Now I see the pics. Perhaps the proxy at work blocks the hosting site.
1st pic: This shows the 10,5cm leichte Feldhaubitze 18 ... considered
medium or even
light artillery by the name already. What I listed in my post were
heavy artillery pieces.
2nd pic: This shows an anti-aircraft setup which was not that numerous to begin with. What I was talking about was the ordinary ground role for the MG, either as "light MG" without the tripod or as "heavy MG" with the tripod.
You may not see a reason for me being this detailed but I am a fan of military history and a plastic modeler so I do have a penchant for accuracy and details.
