In recent years they made CN film. Some years earlier, slide as well, but I haven't seen Ferrari or 3M labelled black and white film for ages. They were a major player in document, process and x-ray film, so they know or once knew how to make black and white materials... But I rather suspect they intend to capitalise on their colour competence - with Kodak out of slide, Fuji almost out of CN, Gevaert only making a tech colour film and all of them on the retreat rather than expanding, there are better opportunities in colour.
