Ok, here is the data I have.

Kodak Professional Q-60 Cat 190 7914, list $39.95

Kodak Color separation Guide and gray scale (small) Cat 152 7654 $19.95

Then there is the color chart and 18% gray scale in the Color Dataguide which is still in print. So, Kodak supplies 3 charts from about 3" x 7" (small) to 4x5 (Q-60) to medium (5x7) in the Dataguide. Then there is the checker which is about 11x14".

The attached photo is of the Kodak Dataguide chart and the checker.
