I think I could scan/print it out to be pretty close.
Page 29 of the 1980 (silver cover) Darkroom Dataguide has (almost) the same formula and colour patches.

The only difference in the formula from the 1970 version is that the 1970 guide included both Avoirdupois and metric measures.

Unfortunately, the 1980 Dataguide doesn't have the neat paper samples that the 1970 Dataguide does.
