Friend from work has recieved a gun from his father and wants to get rid of it. It is a Model 70 Colt in Nickel that has different sights on it than factory and Pachmayr grips. He wants $350 for it. Not perfect, but nickel is not chipping off and it still seems pretty nice, maybe 7 or 8 out of 10. Should I go for it? What is it worth? I can't attach a picture for some reason or I would do that.
