I like finding old photos of the NÃ¼rburgring Nordschleife and I stumbled across these examples courtesy of sebbbl on the Fastlane forum. While the exact identity of these images is unconfirmed it is believed they were taken on 5 August 1953, just after the German Grand Prix. The cars are thought to be Lancias in testing for a 1000km race which was held a few weeks later.
The photo above looks to be coming down the hill into Breidscheid just before crossing what is now commonly known as Adenau bridge. The second and third pictures (shown below) are obviously from pit lane and the last picture is a bit harder to identify where it was taken, but my guess would be somewhere between the Wehrseifen and Breidscheid corners.
