I believe that Germany and Argentina have some history together. Oh say about 65 or so years ago. Just sayin’.
Definitely, even longer
I have a German-made Oberndorfer Argentine Mauser made in 1905 (this is positively cherry - Argentine Crest - all German proof marks, etc.). Odd caliber - 7.65 Argentine cartridge... I don’t think this was even fired.... has a green leather shoulder strap and a silver plated bayonet with quillion.
