The OB was the old standard Kodak filter for graded paper.
The OC has more a more limited spectrum. It is suitable for
any paper which is "safe" with the OB filter but the OB
filter should not be used for papers specifying an OC filter
such as modern variable contrast filters.
I think Kodagraph was a document copying paper, Dave Valvo
will know.
