Thats a newton action, not mauser or springfield. The stock seems rather plain, good chance the oringal surkamer stock was replaced. its missing the rear sight and has been drill for scope mounts. The value would in my option be pretty limited because of these issues, likely around $1000. The best way to sell it would be list it on gunbroker for .99 auction with no reserve. There is are many collectors watching gunbroker and it will be bid to a fair price.
