Hi Marine......welcome to TFF.
What you have is a Model 1895 Chilean Mauser. If in original condition, the caliber is 7x57mm.
It may be an Army or Navy (anchor stamp) rifle, short rifle, or carbine.....can you post some pictures? Sharp, clear, well lit, pictures, full length, both left and right sides. Also clear, sharp, closeups of any numbers, markings, engraving, or unusual features. This will help us determine what you've got, and it's approximate condition and value.
