"Known origin." Hmm. Even if you knew the company and location of their factory, what would that tell you? Lots of industrial processes are proprietary, even from known locations.
Also, much film manufacture is batch-processed. Not like cars rolling off the assembly line in continuous fashion, 24/7/365, but stopped and started intermittently.
The fact that the film packaging indicates made in EU, should confer some (at least minimal) assurance of adherence to ISO9000 standards, should it not?
I'm still amazed, in the case of Kodak, that more film users with nationalistic tendencies don't object to some of their product being manufactured in a particular large Asian country ("ahem" PRC "ahem"). Doesn't matter to me, as long as standards are maintained.
With proper manufacturing principles (i.e. like Intel's "copy exactly" methodology), it shouldn't matter, from a product quality standpoint, where the factory was located.
