I think it's made by Ferrania. I have 2 rolls that came with one of my ebay cameras, the "redscale" kind, which is nothing but film respooled upside down, so the base acts as a red filter. They also sell film that's designed for cross processing (which you can do with any film I believe), and slide film made using the same emulsion of Agfa RSX 200. I can confirm that the Redscale 100 I have says "made in Italy", and the barcode from the cartridges come back to Ferrania Imaging (of course, the Fomapan cartridges also have a Ferrania code). And by the way, said redscale film can also be made at home by respooling color film upside down
