I assume he's re-perforating 16mm film...? As far as I know, Kodak simply doesn't manufacture regular-8 any more.
International Film buys the stock from Kodak as a special order. It is listed in the Kodak MP film catalogue with a several roll (400ft roll) minimum order. John has regular 8 spools and cans. (the spools that the film I last got from him were Soviet in origin) a 400ft rolls gives 12 standard spools as the leaders mean you need 33 feet for each roll.
I understand that it was John who persuaded Kodak to make the stock available as a special order.
