Here's one I did 14 years ago. It was pretty beat up looking before hand. Part of a good process, is to never sand the original if possible. This was done entirely with finish remover and scraping. Then went back on with JM's London Oil finish.
Note it would have been good here to have used some stain work to level out the color right behind the pistol grip. Also some will notice that the grip cap is modified. Originally it would have had a "lip" in the front, but at some point the ISSF rules disallowed that and a previous owner had modified it. I just tried to polish it up.
