Thank you for your replies! Much appreciated. It might well be that it is a supermarket film, either from Germany or from a shop in Egypt.
@rodeo_joe|1 , I am asking just out of curiosity, indeed I'm in the process of scanning my old films. This one has a strong green tint, unlike Fuji or Kodak from the same period. But Photoshop will help.
Thank you all again,
Best regards,
Georg
