German Leadership

Hitler, Speer, Porsche etc study a gun ....

A photograph related to one recently posted, the occasion of which was identified by FTG. It shows that the weapon being examined by the exalted company was, in fact, an armoured vehicle. I have to say that I have failed to identify the vehicle; the fact that what is probably the driver's hatch is open and blocking the view, as is the presence of so many bodies on the deck, has defeated me. Could it be a PzKpfw III or PzKpfw IV (possibly Ausf J) with a heafty bolted-on additional frontal armour plate, be the answer ? Any suggestions would be of interest to me. Best regards, JR.
