I resisted the temptation to get the hairdryer out, hung the film in the shower up and went for a walk. Then I came back and scanned each cut strip (Epson V700 & Lomography Digitaliza @ 6400dpi, 16bit Greyscale) into Lightroom. Frames 1, 2, 3 and 4 were no use, just blank or blurry shots of a non-descript road surface.
From the age of camera, these are probably sometime after 1963. The car in the background of Frame 5 feels about that age. They're presumably a local festival of the sort that is very popular in this part of the world. (Interestingly between frames 7 and 8 the film turns upside down. To me, this indicates that the film was used in two different cameras and changed over by someone who knew what they were doing. There are no lost frames or light bleed)
Update 1.2: Pictures 5, 6 and 7 show a carnival procession (on Monday before Ash Wednesday) in the town of Mühlheim an der Donau. The figures are called "Schellennarr" and are caricatures of traditional mill boys. They wear a suit made of painted linen, a wooden mask, a hat like a hopper of an old mill ("Mahltrichter") and wooden "bells" are attached to the suit. These carnival fools ("Narren") distribute sweets from their white sacks. Such figures and processions are typical for the "Swabian-Alemannic Fastnacht", which is quite different from the carnival on the Rhine, e.g. in Cologne. Picture #5 is particularly interesting: At that time normally only the men wore the costumes, the women were spectators. But here a young woman can be seen wearing a costume! (and taking part in frame #7 too ;) This even is still happening and the webpage http://www.schellennarr.de has up to date information on the carnival fool guild ("Narrenzunft") of Mühlheim an der Donau.
