Instruction Book 1917 but Used by the SS

[Jeroen wo2]

Hi Guys,

I want to show you a Instruction book from world war one.
The rare thing is that it was used by an SS Sturmfuhrer.
In the book you can read:

.....
Sturmfuhrer
Den SS Kompanie Flandern
1942

Now comes my question.
The previous owner from wold war one had as chef Hermann Goring!
What sort of was this guy of some staf member?
Is it possible that the name written there was done bij Hermann Goring himself?

Kind Regards, Jeroen.
