I first started developing my own film in 1961. Like many newbies I immediately wanted to try every available film in every available developer. Adox KB-14, KB-17, and KB-21 were readily available. The numbers were actually the DIN speed numbers equivalent to ISO 20, 40, and 100. I believe that Adox also made a higher speed film only available in Europe. I tried all three and for a year or two shot a lot of KB-17. I settled on using FR-22 developer. It came in 1 ounce bottles and was a one-shot designed for slow films.
KB-14 didn't seem to have much finer grain. Both Ilford FP3 and Kodak Plus X had finer grain than KB-21. If you enlarged big enough, at least 11x14, you could notice that ISO 20 Agfa Isopan FF and ISO 40 Isopan F seemed to have sharper grain than the Adox film.
If anybody wants to come by, go through my boxes of negatives and contact sheets, and make some sample prints...LOL...I still have all of them. You might even be able to print up some sexy pictures of your wife's grandmother. Just to study the grain of course.
By today's standards they were all grainy films. Even Kodak dropped Panatomic-X and the motion picture film of the same speed, Eastman XT Pan a few years ago. Faster films had fine enough grain.
