John, thank you for the size information. I am trying to figure out how to cut down film for my Busch Pressman C which is "2 x 3"". If you are not able to get Adox in ISO/ASA 25 or 50 and only in "3 x 4"" then I can make one cut to make it work. That's ok with me it's not that hard. If I have to use 4 x 5" in ASA 25 then I will make a press cutter or just adapt my back for the Graflex roll holder I have.
