Not quite. Dynacolor was a film company based in Oklahoma, Ferrania was a film company based in Italy. Eventually 3M bought them both, and later spun off Ferrania with the assets of the former Dynacolor - still based in OK. Ferrania is still based in Italy.
I've not been impressed with their film. However, they still make 126 cartridge film, available through the Frugal Photographer, so if you want to shoot 126 cartridge, they're the only choice.
Basically, they were the default 'store brand' until Agfa took that business over - consumers preferred the Agfa store brands to the Ferrania store brands. Now with Agfa gone, I guess Ferrania is back into the game.
It is my understanding that Ferrania has been bankrupt for more than a decade - a quirk of Italian politics and right-to-work laws won't let the company fold. That's just what I hear, no proof of that.
