Hello Douglas,
It is good to hear that you are making some discoveries in Brazil. The caliber of the Mauser C96 which you are describing is a 9 mm Export which is the same size as a 9 mm Parabellum but a few millimeters longer in length.
I shall send you a page image from an old catalog which I own showing the cartridge and giving its DWM number.
Regards,
Albert
