Michael, did your father ever photograph away from the start/finish area, on the actual Südschleife?
Rob, most of the pictures that Harry took depict the start/finish area as well as pits and paddock. I will post a few pics (or even did so already) that were taken near Schwalbenschwanz and in the Brünnchen section. Unfortunately I do not have any images from the Südschleife, however, there are people providing information on that.
A friend of mine runs this lovely website (German only): http://www.nordschleifologie.de/
Please click on "Südschleife" in the menue and you will find pictures of the southern track including bike races
Another nice website is "Pro Steilstrecke": http://www.pro-steilstrecke.de/
Go to -> Mythos -> Südschleife
I am sure you will browse these sites for hours.
Harry, btw, is a good old friend. Unfortunately my dad never took me to the races; Harry made me discover the thrill of motor racing ...
