Grip renovation

You are about to have 10 guys tell you not to do it! But before you decide. What do you consider a collectable Luger? What model is it? What is blue and metal conditon? What condition are grips now? Do you want to just clean oil and dirt from grips? Please don't use the Murphy Soap and water method. Do they in your opinion require checkering to be sharpened? [I did't say rechecker-just improve what is there] It is your Luger and obviously you want the grips to look better. Go for it. Feel free to email for more detailed info.
