From '38 to 1951, Kodachrome was made in sheet film, with an ASA of 8! and also type B, with a stunning 10 ASA, as I recall was used for flash.
I took many slides with the original Kodachrome 25, and even though many of them are 50 or so years old, they still look great. The developing process was changed later, for the 25, and I quit using it then, as it lacked, I thought, the quality of the older processing images.
Delano was a master photographer, only a master could have made so many great images with such slow film.
