what type of film is silver tone

[blade_o]

Hello, I shot this film in a high school photo class about 3years ago and im trying to figure out what it is. It was cheap stuff called silver tone, I'm guessing it is some other kind of film stock re-packaged, ISO 100. the sprockets on the film (35mm) read iso100/21 670-40 2or
if any one knows or has any ideas that would be great, the base has a purple-ish tinge to it.
thanks

I believe its Agfa APX100. Agfa, AFAIK, is defunct, so find some and grab it. Never used it myself. We shot bulk load T-Max in highschool.
Of course, I could be wrong.

I did a search for silver Tone and found this on APUG: (there was a url link here which no longer exists)

Yup, APX100. It's gorgeous...a relatively new emulsion for me but I'm quickly learning to love it.
