If you're trying to match COLOURs, try:

They have a bunch of stuff about colour management,
including grey cards.


If you're trying to match COLORs,
The THIRD edition (1966) of the "Kodak Color Dataguide"
has both gray scale and color control patches. (along with a
whole bunch of dedicated circular slide rules for things like
color correction with filter pack changes)

By the fifth edition (1975), they had dropped the color control
patches, but at least they kept the gray card.
