It's perhaps worth looking at the Dilute DK-50 formula that was in use in the early 1960's as this is closer to the formula here. Geoffrey Crawley puublished it in his series of artcles 1960/61 on Developers in the BJP it was in subsequent Anuals for many years in the Fornulae section.
DK-50 is one of Kodak's variations/evolutions of the earlier Wellington & Ward Buffered Borax formula, lurking somewhere in an obscure publication there's probably a Borax version D-50. Kodak tried and published a few Sodium Metaborate (Kodalk) buffered versions of common formulae including DK76 and DK76b.
