I have just added one more document to my post "Once More, With Feeling: Deniers And Aktion 1005, 10 Years Later". It not only explicitly mentions both SK1005a and SK1005b, it also calls them a task of the Reichsführer-SS Himmler which was a secret Reich matter and which was given to Paul Blobel - something Mattogno and his freaky sidekick Graf have always desperately tried to deny.
That means that thus far at least 5 German wartime documents mentioning the designation 1005 are available to researchers (not including the letter from Müller to Luther, the treatment of which Mattogno completely botched, and not including the documents that clearly speak about this action but do not mention the designation). Wheareas Mattogno claimed that there are none, which, to repeat, makes him a fraudulent clown.
