Have lots of questions on a Colt MK IV series 70 I got in a trade (saved it really from an incompetent owner :bang_wall. The finish looks to be a satin, I think a nickel finish maybe? But there is lots of spots and markings on it. Is there a way to clean those up or am I SOL in this case. I am just trying to get information on the pistol. This is my first colt gun (have couple of citadels and RIA that I used reuglarly). What can be done about the finish and some advice on what to do with the pistol. Here are some pictures of it disassembled. Also is it normal for them it to have blued grip safety, trigger, safety, and slide release? I am wondering about the barrel bushing as well if that is normal or special for this pistol? I know my RIA and Citadels don't have that style. It has wrap around grips with gold pony coin in the grips. Also like to mention this is what it looks like after a friend of mine helped me clean her up. This thing was dirty as can be and looked as if the guy shot it and then never cleaned the thing for a year or more! Lots of questions and just curious about the gun in general. Hope some of ya'll can provide me some insight into this. THANK YOU!
