Which European manufacturer was paid royalties by the United States Government for patent infringement over the Model 1903 Springfield Rifle?

From 1905 to 1914, the U.S. paid $200,000 in royalties to Mauser for patent infringements on Mauser's rifle designs. That included 75 cents per M1903 Springfield Rifle produced, and charges for stripper clip production. Mauser did not actually sue, but both the United States and Mauser's attorneys agreed that the patent infringement had occurred and that any lawsuit would be won by Mauser. The situation was started during the Spanish-American War, when the United States forces were taking large numbers of casualties due to the superiority of the Mauser rifle being used by the Spanish forces. Rifles captured on the battlefield were sent to Springfield Armory, and were reverse engineered to come up with a design which was adopted by the U.S. Government as the Model 1903 Springfield Rifle.
