If I might return to the document thing for a moment, while looking at the document scans on
the website for the Wannsee Conference House Memorial and Educational Site where SnakeTongue found one of the documents he supposedly used to prove the March 26, 1942, Rauff document was a forgery based on the "office code", I chanced across documents that prove he has
no idea what he's talking about in his "analysis".
He said,
Unfortunately for SnakeTongue, the invitations to the Wannsee Conference sent under Heydrich's signature prove him
completely wrong about the above.
On November 29, 1941, Heydrich scheduled a conference to discuss the "Final Solution to the Jewish Question", and sent invitations to a number of leading Nazis. The invitation was sent to Martin Luther of the Foreign Office (available as a high-quality PDF scan
here), and asked him to attend a conference at Wannsee on December 12, 1941. As you can see on the upper left, the document was sent from Adolf Eichmann's RSHA department for Jewish Affairs and Deportation, Referat IV B 4, to which the department's Verteiler, Rudolf Jaenisch, gave the typewritten filing code 3076/41g (1180), and it was sent from Berlin (where Eichmann's IV B 4 was located, at Kurfuerstenstrasse 115/116).
SnakeTongue would have you believe that this was because Heydrich knew that IV B 4 was "the department responsible for the subject discussed in the document", which is why it appeared on the document even though Heydrich signed it, and the lack of such a "responsible" department on Rauff's letter of March 1942 means it is a forgery.
Except that's not why IV B 4 appeared on that document at all. It's because that letter was written by Eichmann himself in Berlin, which is why it bears his institutional symbol (Heydrich regularly got Eichmann to write his letters for him), and Heydrich merely
signed it.
How do we know this? Because on January 8th, 1942, Heydrich sent out a letter rescheduling the conference at Wannsee: since the December 9, 1941 meeting had to be canceled, the conference would now be held at Wannsee on January 20, 1942. You can see a high-quality PDF of that letter Luther received
here.
The first thing that should become apparent is that this document was
not sent by Eichmann's IV B 4, something that should not have happened according to SnakeTongue. Instead, it was sent by Heydrich's office directly, from Prague (not Berlin). And, since Heydrich as "Chef der Sicherheitspolizei und des SD" had no institutional symbol as a RSHA referent, the filing code on the document (half typewritten and half handwritten) is given as an abbreviation of "Chef der Sicherheitspolizei und des SD", C.d.S, and is filed under 18/42.
Why the difference, if both documents are dealing with the exact same subject (the scheduling of and invitations for the Wannsee Conference)?
That's because the first document was written by Eichmann, which is why it was tagged with Eichmann's institutional symbol. It was sent by his office, and even though it was signed by Heydrich, it was Eichmann who was responsible for the content of the document.
The second document, though, was sent from Heydrich's office in Prague (where he was Acting Protector). Since Eichmann was still in Berlin, Heydrich couldn't get Eichmann's office of IV B 4 to write the new invitation. Instead, it came from his own staff in Prague, and was labeled and filed accordingly (the typist of this document, unlike the typist who typed the first document, didn't even know where it would be filed [other than it would be in a file opened in the new year, 1942], which is why the filing code was handwritten in later).
Two documents, dealing with the same thing, but with different filing/office codes, because they were created by (and thus were the "responsibility" of), two
completely separate sets of RSHA personnel.
