Those DWM sporters are another story. In those innocent pre-WW1 days it was a common practice to include some sporting rifles in the military calibers into each shipment of military rifles to foreign countries, meant as gifts/bribes to the friendly decision makers. Mauser used their army type C rifles for these purposes, but DWM was without an own commercial production. So they had their "present/promotion" rifles either made up by independent Suhl or Zella-Mehlis gunmakers, apparently sometimes even using pre-shaped stocks by the DWM subsidiary Mauser. Especially famous are the 7x57 "Plesier" sporting rifles on M93 actions with long, octagonal barrels, sent to the Boers in South Africa with the shipments of Military M95 rifles. South American countries of course expected the same friendly treatment, sometimes even mentioning the number of sporters to be included in the military rifle contracts.
