The thing about the rifle is it says it’s a M1916 chambered in 308win or 7.62 which leads me to think it’s a Spanish Mauser but one of the proof marks it has which is located on the underside of the rifle on the magazine is a circled cross and I can’t match it with any other Spanish Mauser proof marks. I’ve had my Mauser for a few years now I inherited it through my grandfather but just recently I’ve decided to bring it out of the gun safe and do a little research on it to find out more about it but everywhere I go to get it examined for appraisal I run into a dead end because it has very few proof markings and the ones that it does have I can’t find any information on them local gunsmiths just scratch their heads and shrug their shoulders at it and say I should take it to get it examined at a gun auction but I figured I’d give this a shot first
