Dear Andy, what do you need to know? The facts are: In the process of closing the Agfa film company it was cheaper processing all remaining raw material to film instead of disposing it. This gave huge amount of 35 mm APX100 master rolls (35 mm material: Gray 135Ám base). Most of the master rolls were frozen are perhaps still frozen.
APX100 is a fine film. The films made from the last batch were always ridiculous cheap. I bought MF films for 1.65€ per roll (around $2) and 35 mm films for 1.95€ per roll (slightly more than $2) and still have ~ 150 rolls of MF and 50 rolls of 35 mm films in my cellar.
