FWIW, I have the 1921 edition and the 1934 edition of
this. I suspect it was replaced by the small "Processing and
Formulas" booklet when the _Kodak Reference Handbook_ came
out about 1940. The book is much more complete than the KRH
booklet. The 1921 edition was published before any of the
familiar Kodak formulas, like D-76 (1926) or D-72 (Dektol)
existed. The film developers are Pyro types, something Kodak
seemed to avoid later.
Neither of my editions mentions a previous one so there
is no way of telling when Kodak started publishing them.
This is the sort of stuff people were throwing away not so
long ago, now considered rather valuable since the
information is hard to find in current sources.
Congratulations on finding this and recoginzing its value.
