Argentina was one of the three customers for Mauser’s first smokeless powder rifle, the model 1889.

1889-Belgium
1890-Turkey
1891-Argentina

The best rifle in the world at the time. The 7.65x55 cartridge is also fantastic, especially with modern powder. It and the 7x57 were actual Mauser chamberings, while the 8x75 Mauser, wasn’t a Mauser at all, but was rather a product of the 1888 Rifle Commission.

AS well as the Colt offering of Mr Browning's water-cooled machinegun. Which became the M1917 when the U.S. got around to adopting it.
