It looks quite like the Rollie Digibase 200 ISO where the grain is concerned. You don't think it could be the same film under a different alias? Digibase has a acetate base and cannot be torn, it is thin but doesn't curl as you described.
All the same: i have datasheet.
Agfa-Gevaert Aviphoto Chrome 200
200-400 Asa for optimal colors
Built-in UV-filter to avoid blue and unsharp images under UV-radiation.
Seperation layer for optimal color-seperation and saturation.
Grain yes but doesnt matter much if you have razorsharp lens.
had N200 and Pan 200, Pan200S(still have) also quite grainy. but good.
Agfa has multiple Panfilms starting from 20 to 400.
only must find out which one is which when brands are changed. which corresponds which one. Maco must give answers.
sometime films are sold under different asa. over or underexposed..
e.g. Agfa Ultra 50 is overeposed H100. contrast will be increased. so it can be exposed at 100.
Have still some 70mm rolls and 126mm one roll 46m.
