Spanish Luger Manual

[spacecoast]

I acquired this manual in a recent purchase and would like to know more about it. With the exception of a few scuffs on the front cover, it is in excellent condition and has a cool foldout inside the back cover with pictures of both Old and New Model Lugers. Does anyone have information as to age, origin and which Lugers it may have been intended to accompany? It was included with a leather Luger case from a gun shop in Buenos Aires, Argentina, pictures of which I will post later.
