Today I acquired a Ruger Mark 1. It's a "pre-warning" gun as in it doesn't have the warning label on it like guns do now. The blueing on it is near perfect, only very minor scratches that can probably be buffed off. Nothing is chipped off except some paint on the eagle on the grip. It's SUPER CLEAN inside and out. It has a number on it I assume is the serial number. I'm not sure when it was manufactured. Has the original mag which is also in amazing condition. How much is this worth? I've looked on GB to try to compare but the values vary so greatly due to so many factors it's hard to tell and I know nothing about these guns.
