Being the commensurate gun tinkerer that I am, I can see the attraction of using the occasion to turn the lemon into lemonade by using it as an opportunity to learn a new skill in the process, such as engraving, burnishing or the rust bluing...QUOTE]

Right now the gun looks fine. A re-blue will stand out like a sore thumb.
I would just leave it as-is.
