It would be pretty cool if you are able to reunite with the rod but you already know it’s a long shot.
As an alternative, why don’t you consider having a replacement built for yourself?
If I were you I would incorporate some of the original Rods features on the new one, including your misspelled name and perhaps a special message like “thanks Kevin.”
Just some thoughts to keep you moving forward with your sobriety, remembering your past and celebrating what you’ve already accomplished.
Good luck !
