Service
The Standardmodell of 1924 was used by the SA and the SS and was exported to China and South America. According to the manufacturer, the Model 1933 rifle was only sold to the Deutsche Reichspost, the German post office. The rifle was named Gewehr für Deutsches Reichspost. Part of this production was actually purchased by Nazi organisations or by the Reichswehr. The Wehrmacht, through requisitions, might have used it during World War II. Bolivia purchased the Standardmodell in the 1920s and used it in combat during the Chaco War. Its enemy, Paraguay, fielded Standardmodell rifles bought during the 1930s. The rifle was also ordered by Honduras. The Standardmodell saw service in China. In the Chinese National Armament Standards Conference of 1932 it was decided that the Standardmodell was to be the standard issue rifle of the National Revolutionary Army. It started being imported from Germany in 1934, the first 10,000 were being bought for the Chinese Tax Police., and production in Chinese arsenals also began in 1935, first under the name "Type 24 Rifle", but was soon renamed to the "Chiang Kai-Shek rifle" after the Generalissimo. It was used during the Chinese Civil War and the Second Sino-Japanese War. The Imperial Japanese Navy reportedly used rifles captured in China. The Ethiopian Empire bought 25,000 Model 1924 and Model 1933 rifles and carbines, and fielded them during the Second Italo-Ethiopian War. The Buenos Aires Police also bought Mauser Model 1933 in rifles and carbines configuration, the latter with a barrel. The Argentinean rifles and carbines differ from the other Standardmodells by having an extended arm on the bolt release.
