Oh yes! Kodachrome 64 ASA forever! I have my Dad's 35mm [mostly] Kodachrome slide collection. When he started it was ASA 10. You needed a bright day because unless you were wealthy your camera lens was small and thus not too great at gathering light. I know there are Kodachrome slides in there of Espee Daylights. One of these days I'll start going through them.
