depending on the make, 300 is a decent asking price. german K98 mausers in perfect condition go for 1000 but once they are sporterized they drop to around 250-400. other mausers like czech vz24s or turkish mausers top out at around $400 in good condition so it will depend on the markings on the rifle to help verify it's origins. however I would say regardless of the make and caliber then I would say you got a good deal.
