I couldn't find a definite info on where TRI-X for 135 is produced these days (location of the factory). If there are more than one production facilities, which one supplies the european market?
Also interesting to know if the film is produced in one facility entirely or flown a couple of times around the world (e.g. for packaging, etc.) until its done.
And only one finishing and packaging facility - also Eastman Kodak's facility in Rochester, New York, USA.
What does vary greatly is the distribution route. Kodak Alaris buys the film from Eastman Kodak, and then sells it to distributors, who sell it to either retailers or other distributors, etc., etc. until it is eventually purchased by an end user.
