Hello,basically the spanish mausers were made in 2 action types ,the 98 and the 93or 1916,the 98 is a beefier action and usually will be found with a straight bolt,the 93's action is smaller and usually has a bent bolt,some spanish mausers will have a crest on the top of the receiver along with the arsenal oveido and a date,these markings are usually on the 93 actions and are usually chambered for the 7mm mauser caliber,there were some special rifles chambered for the 308 or 762x51 caliber ,if your rifle may be import stamped ,look on the exposed part of the barrel ,near the front site for very small stamped markings ,if you find any markings they will usually have the model number and the country from where it was made ,it may say something like this m93 7mm spain,then the importer like CAI and virginia something like that ,if theres no import stamp thats a good thing and collectors will buy non import stamped guns more over import stamped ones ,just because the stamp isn't an original stamping.
