The Metol level struck me as different from memory and my recipe spreadsheet had the components as it appears at: http://www.2spi.com/catalog/photo/kodak-d19.html I've actually not used it but had recently looked at it when guessing at some ratios on a test here.... Is yours direct from the publication and this site and my original source (long forgotten to me) is a likely typo transferred along or different generation recipe? Have you used it and in what application? I'm on a mission lately to clean up my records and verify my recipes before printing out a recipe book for my darkroom.
The formula above is I'd guess D-11 not D19. The current commercial D19 is most likely the later variant D19b: D-19 Metol 2.0 gram Sodium sulphite (anhydrous) 90.0 grams Hydroquinone 8 grams Sodium Carbonate (Anhydrous) 45.5 gms or (monohydrated) 52.5 gms Potassium Bromide 5.0 grams Water to make 1 litre. Later this was reformulated as D19b and was a standard developer with a variety of uses. D19b / Ilford ID-19 Metol 2.2 gram Sodium sulphite (anhydrous) 72.0 grams Hydroquinone 8.8 grams Sodium Carbonate(anhydrous) 48.0grams Potassium Bromide 4.0 grams Water to make 1 litre. The more modern Ilford PQ version is: ID-72 Phenidone 0.22 gram Sodium sulphite (anhydrous) 72.0 grams Hydroquinone 8.8 grams Sodium Carbonate(anhydrous) 48.0grams Potassium Bromide 4.0 grams IBT 1% soln (Benzotriazole) 10ml Water to make 1 litre.

Just to confirm the formula listed is D11, and is in Publication J-1 as: D11 Metol 1.0 gram Sodium sulphite (anhydrous) 75.0 grams Hydroquinone 9 grams Sodium Carbonate (anhydrous) 26.0grams or (monohydrated) 30 grams Potassium Bromide 5.0 grams Water to make 1 litre. Ian
