Let us assume that an old formula, as mentioned by Ferrania themselves, used methyl mercuric iodide or cadmium nitrate. Both possible in products made in Europe (AFAIK at the time), but forbidden in the US. Today, they are forbidden in Europe and the US. This makes manufacture of the product impossible and the sale of a product containing them impossible.
There are grandfathered products that were made by companies that went out of business, that used banned chemicals and are allowed to be sold but not made (again AFAIK).
These are fairy tales made up to show real chemicals in an unreal situation. The fact is that whatever chemicals were used in Ferrania / Scotch products are no longer available or manufactured for one reason or another. So, here is the premise - make a cake with no flour! Too hard, I'll give you the flour and take away the eggs! If you can't do this in 30 mins, you are chopped!
Simple as that. You have to make a product missing a critical ingredient and you have to find a substitute. I hope they do at Ferrania or the product may be quite a bit more like TIP products that we would like.

Dear PE, thanks for your reply. I understand and agree on the potential difficulties. However, note that the C41 products were made by Ferrania up to the end of 2009; this is about 5 years ago; not so long. I would guess no critical chemicals have been banned since 2009?
