Saad, your original questions suggest you have no gunsmithing experience. Also, you seem aware that many so-called gunsmiths can do more harm than good. If you do not have a good set of hollow ground gunsmithing screwdrivers, I'd suggest avoiding even disassembling for cleaning. You have a nice gun and it is not one to use as a learning tool. If you desire to do this type of work, it is wise to start with cheap common guns rather than a higher quality piece.
Where are you located? Perhaps someone here can direct you to a gunsmith near you that can do what you wish without ruining your gun. I agree with those who advise you to do as little as possible to make the gun look good without a total restoration. Always keep it at least ten feet away from buffing wheels and sandpaper. Good luck. Let us know how it turns out.
