Yup, glad to have you here.
Look at the markings, it's probably a "Mark X" Mauser, which means it's a commercial Yugoslavian made action. Good in every way. Many of these are found with the classic but now dated glossy finish on an equally cdated monte carlo stock, as their 1970's vintage would dictate. Cosmetics are a matter of preference. Some were built with more "Classic" stocks, and sold as "Churchill" Mausers. All are mechanically identical and all are fine rifles.
