Jeff, page 27 of the 1970s Kodak Darkroom Dataguide has the HT-2 formula and the color patches. You never got one of those Dataguides in any boxes of equipment??
I think I could scan/print it out to be pretty close.
Thanks - looks like I need to find a copy of the Dataguide now! I looked and I don't have a copy. Is there a preferred version out there?
