A friend found a model 31-1 nickel that He thinks is new in the box. No cylinder turn line or carbon on the cylinder face. Didn't get the SN. The box is like new and has the wrapping paper and the tools. What color should the box be? Should the grips have the diamond around the screw? The guy is asking $600. Is this too much? Thank You for Your help. What tools should be there?
