See above—the bag-in-box chemistry for these processors is no longer available—it would have to be something else. I'm thinking some sort of custom dip-and-dunk machine, but the re-exposure steps might be tricky.
I'm sure that a reliable European Kodachrome processing service would be welcomed by those who, like me, have stopped using the film because of the long turnaround time and inconsistent results of Dwayne's. Presumably this would need the blessing/co-operation of Kodak, if only to facilitate the issues relating to the fact that Kodachrome is normally sold in the UK (and presumably the rest of Europe) with processing included in the film's cost.
I think that the US is the only place where K64 is sold non pre-paid, due to the anti-trust lawsuit that Kodak had way back when.
I personally find it more unusual not to have process paid slides. Thats what I grew up with (Agfacolor....Anybody remember that)
"Flatter Me, and I May Not Believe You. Criticize Me, and I May Not like You. Ignore Me, and I May Not Forgive You. Encourage Me, and I Will Not Forget You."
Kodachrome has been sold without processing included in Canada for a few years now. Previously it was sold with processing included. I don't know when it changed.
