This is a Golden State Arms Corp Mauser Mk1 model 12014 chambered in 30-06. These are pretty rare and excellent shooting rifles, around these parts this would make an amazine "all around" hunting rifle....deer, hogs, coyote (maybe a bit much for coyote but who doesn't want to turn a coyote inside out when it gets too close to your property and animals).  It's a 30-06 Mauser....Solid, well built, smooth action, needs a good scrub down, other than that beautiful gun.
