Two things :
It surprising how clean and true the base of the grip panels are. Most revolvers of that age and condition look like they've been used as a hammer.
It would be interesting to see how that old iron would look after a long Ed's Red bath and a thorough scrub with bronze wool. Might turn out to be quite attractive.
Of course , if your goal is diy bluing , it is your gun.. That one certainly is beyond "fine patina" and into the range of somewhat corroded. I am sure that photos of various stages of your process would be well received here.
Good luck in your project.
