The "SO" films were originally special order. SO-366 was balanced for
daylight or electronic flash while Kodak's standard dupe film at that time
was balance for tungsten light and the long roll "Sickles" type duplicator.
It was lower in contrast than an in-camera type film and pretty easy to use.
As I recall they made another "SO" optimized for Kodachrome dupes at one
time.
Whats the EI on this stuff?
I'm going to do a reversal on this and do some chemistry fun with it
in the darkroom.
Also I've come across a hundred rolls of Kodak P1600. time for more
fun. I know enough about it, I found a datasheet on it but still
unsure the exposure latitude if anyone knows..

Pretty slow, not a problem when used for it's intended use, but start at
around EI 2 to EI 25 for your first test roll and bracket.
