The data sheet isn't going to tell you this. The point is that it should react similar in Pyrocat as Efke 100 since the only significant difference is the Pina sensitizer. Efke is the actual manufacturer of this film. Maco just rebrands and distributes it.
No (to my surprise), but I have a few pictures on www.alternativephotography.com including some IR shots. Find me as Ole Tjugen under Scandinavia -> Norway.
Freestyle stocks the Maco IR films (820c,820c AURA) in the 8x10 size. Supposedly there were a few other places, I don't recall who they were at the moment.
