cmo,
I tried to do this once before as well here: (there was a url link here which no longer exists) Not much response and I would say that is because it is spread far and wide throughout the APUG threads. After the above attempt I did some digging and what I came up with was this post I made in a different forum.
"Arista II = Old Agfa APX 100/400
Arista Premium 100 = Kodak Plus-x
Arista Premium 400 = Kodak Tri-x
Arista.EDU = Fortepan (Hungary)
Arista.EDU Ultra = Fomapan (czech)
Rollei Retro = Also APX
Legacy (freestyle) = Fuji Neopan and 100 Acros
Efke = All these are made with the old ADOX formulas (croatia)
Adox (films however) = CHM 125/400 Made by Ilford, CHS 25/50/100 Efke
MACO = Never made film just re-badged it (Rollei & MACO)
Bergger = old stock was made in Fortepan Plant, may be moved to Ilford
Quick note: As of the sale of Ilford in 2005, Ilford no longer re-badges any of there films yet there is old stock still out there for sale, like the ADOX. As of 2007, Ilford agreed to make Bergger films, but they are not Ilford emulsions, they are Bergger’s formulas.
I think there is more to go here, but I will have to find my notes"
Since this post I have also found that J and C films were also Fotrepan
Hope this helps and PLEASE, if anyone sees a untruth to the above, please state as so. Rather than speculation, please state how you are to know this. I spent a very long time sifting through the thread to narrow things down to this list.
Thank you
