Re: M98 swedish mauser
1896's cock on closing. 1898's cock on opening and have a third (safety) lug on the bottom of the bolt.
I suggest that you have someone familiar with firearms look at it and determine what exactly you have. While there were many millions of both 1896 and 1898 Mausers manufactures, some have value in their original condition. If you want a sporting rifle, I would suggest you buy one, or trade your rifle for one and leave any military rifles in their original condition.
Good luck
