Does anyone have some experience with this? I have been given some very old B&W 120 film (<1950?), which has been exposed but never was developed. One is labeled ?Adox R17¹, some are just called ?Perutz¹, and one is called ?Agfa L Isopan¹. The owner assures me that the content is of considerable importance to her and her family. I like to give it a try and develop it for her, but I only have ID-11 and Rodinal at the moment. What is the best way to handle this? Any special treatment? Regards Ralph W.
