Finally, I found a way to list the German armoured cars properly. On "kfzderwehrmacht.de", a list shows the chassis names given by the actual manufacturers rather than long military designations. I'll post the correct names here. For each group of vehicles, I will provide year, make and model, and "extra info", together with links to the vehicles affected by the mass changes.

Some makes, however also have to be changed (for example many "Weserhütte" vehicles).
