It's been almost half a century since I've used Adox films, but I still 
remember the different variants quite well.  The three emulsions available 
in North America were KB14 (10 ASA), KB17 (25 ASA, and KB21 (80 ASA); these 
speed ratings are based on processing in Tetanal Neofin Blue for the two 
slower films and Neofin Red for the fast guy.  The KB14 was sharp, almost 
grainless and very contrasty, KG17 seemed to have more tonal range, and KB21 
was quite grainy,with harsh middle tones (harsher than Ilford FP3 or 
Gevaert, for instance) but very sharp.  Perutz Pergrania, a 10 ASA film, was 
at least as good as any of them, when you could find it.
