Nick. Have you visited the Atlantic Wall museum in Hoek van Holland? there is a reconstitution of a German bakery there. They used to make bread for 3000 soldiers there evey day! There are ovens and bags etc... There are even humoristic settings such as the lazarett with the flee control and Herr Doktor checking for vermine on a soldier who has his pants on his knees. (the same scene as in das Boot). It's hilarious.
