    No, the confusion is because Agfa Ansco in the US used different formulae numbering to Agfa in Germany.

    (Agfa-) Ansco 47 MQ is very close to Kodak 61a, superb gradation, very sharp, but usually grainy. I was surprised by the small grain you get with XX.

    Not breally, it's more like D61a is Agfa Ansco 47 with double the level of Sodium Sulphite. quite different.

    It's the same thing if you consider that 5 gr. Sodium carbonate anhydrous = 6 gr. monohydrated

    I have to admit I was comparing to the Agfa Ansco 47 R - replenisher

    When it comes to processing chemistry Kodak lagged way behind their competitors for many years only really bringing out innovative products with HC-110 and Xtol.

    Harold, Agfa-47 use 6g Sodium Carbonate monohydrate = 5.1g ahydrous. so D61a 1+1 use by 10% more sodium carbonate than agfa-47. I think that this isn't very important

    Just to be clear this is not Agfa 47, that is an Amidol developer, and that is very important.
