when you scroll down the FrontPage of the Forum, you´ll find "Projekt Postverträge". When you click on the left side then on "Erweiterte Suche" (advanced search) youll find this page:

Now you can fill in the date and countries and you can see, wheather there are contracts online, or not. You´ll find many thousands, in German, English, French etc.
Hope you have some days off ...
Not getting days off - but I've been looking there each weekend and viewing a different document or two each time. It's a great batch of information!
Danke for pointing it out. I just wanted you to know it has already been of great use to me.
