the kerning I mentioned is a bug in the preview site which I posted before. No kerning needing with the actual Font.
I assambled this myself with the aforementioned Compacta SH Italic.
I would say: "Thats it, case closed"

I layed it over the Original and it fits 100%.
the type was already around in the 80ies, its a pretty old german font, so I would bet all my money they used it, or recreated it perfectly.
