I'll buy just about anything if it's cheap enough!
My guess is that Agfa is the manufacturer ... a *wild* assumption based on the "red" on the package. Agfa seems to be partial to using the color red.
I'd be curious to find out about its age; Although Kodak does imprint "Safety Film" on the margins of its film - to advertise the fact that it is not a nitrocellulose base material "(read *FLAMMABLE* as #$@!) I don't think Agfa has done that for many moons. Interesting.
You should be able to tell more from the film backing itself.
A while ago, I bought a single roll of exposed "Ansco Plenachrome" in an antique shop in North Carolina. My best research indicates that it was probably exposed in the late 1930's. I developed it in Rodinal (made a "clip" test") and succeeded in getting images!! That film DID have a nitrocellulose (incidentally, the main ingredient in smokeless gunpowder) base.
I have tentatively identified this wrapper as Perutz Peromnia 21, that I bought in the 60's. It was very cheap at the time and not anything special as I recall. I hope a member from Europe can confirm the film brand name. That would make me feel better about my memory.
I know I have read on a previous thread that there is a chemical additive that will help with the fog of old film. Why not start a new thread with "Fog in out dated film". That should bring a quick response.
