That would have been Fairlawn, NJ. Processing Kodachrome was not like processing any other film. It required custom made processing equipment. There were only a few places in the world where it was done. All Kodachrome processing for Europe was done in Spain.
Kodachrome had no color dyes in the film itself. Instead, color pigments were added to the individual color layers during the processing cycle. These pigments were extremely stable and the reason why old Kodachrome slides still look so good after sitting for decades in less than optimal storage conditions to downright awful storage conditions.
So if you have any old Kodachrome laying around your darkroom, just treat it like a B&W film and have some fun with it.
