Hello Ron,
You are right; it is odd that the â??00 model is described in a 1909 manual.
I can provide you another very unusual example. Please look at the following scans.

It is extracted from a 1919 book for the German Field Artillery. This book, now in my collection, was used for Artillery Officers and NCOs training. Again the Parabellum described is the â??00 model.
It is absolutely unusual that a training book doesnâ??t describe the correct model.
Let me know your opinion.
Ciao
