My grandfather just passed away and while half the family are gun nuts, no one really wants to keep this rifle. However, before I try to sell it for my grandmother, I would like an idea of what I have and what it is worth. The printing on the barrel says: Fabrica Dearmas Oviedo 1923 2518 is stamped on both the bolt and 2J 2518 is stamped on the barrel. I tried to attach a photo, I hope it works. Any information that people can provide would be greatly appreciated. Thank you in advance.
