I have a old Mauser that is a 7x57mm, on the side of the reciever it says "Deutsche Waffen-und Munitionseabriken Berlin. Then on the reciever and barrel there is a stamp on both saying C6838. Then on the bottom where the ammo goes and is near the trigger it says twice 2N 1805. Those are all the markings. If needed i will load pictures upon request.

Sounds like a M1895 Chilean Mauser. Lets see a picture.

can you give me ur email so i can send them to you and you can upload them. Its saying the files are to big to upload

Yep, pictures are required.
All original military or sporterized??
If military, most parts have a SN (or portions of the number).
Any crest of a country on top of receiver?
Certain original matching, unmucked Mausers fetch a small fortune these days.
Some DWM info...

Theres no crest of any country, the pictures i have are to large to be posted

well it's a small ring german. looks like a chilean without the markings. i'd guess a model 93 or 95

is it worth anything?

and would it matter if i drilled and tapped it for a scope? or should i just get a B square scope mount for it

it's hard to say what it's worth because sometimes one little stamp or feature is more or less desirable to a collector. if you pull the bolt and then look at the bolt face, does it have a flat bottom as you have it right side up and looking at the bolt face?

the small rings were made before metallurgy and gun design were at their peak and so are not as safe as later models like the 98. nothing wrong with your rifle though. i'd have a gunsmith look it over and make sure it's safe and then enjoy using it.
