I dislike this confusion and fog-of-war - why can't things be "old Agfa stock" and "Efke" or whatever it is? Looks like the Adox Pan 25 is some kind of APX25 with a new name. Can't help but smile at the description of the Adox CHS, though:
"ADOX CHS films are still made according to the recipes from the 1950s and are coated slowly on a historic dip and dunk machine. This gives them their special character which cannot be achieved by fast modern spray-coating machines and also enables us to produce micro lots of only 10 000 films at a time.
This way we can keep exotic films like CHS 25 and CHS 50 in constant and fresh production."

I wonder if Kodak could sell more films with that kind of nostalgia blurb?
