There is actually still a lab or two around that process with the K-14M method (the Kodachrome process). A dear friend of mine still shoots the occasional roll of slide film (of which Kodachrome, for its warm tone, is his favorite), and he employs a "professionals' lab" that still - at least as long as they can get their hands on chemicals - develops all types of positive and slide film, and even black and white process film.
