You did ask about re-finishing it, removing the plating, and so on.
My sense was that if you were even considering such things you did not have a true appreciation of the gun as it sits.
You asked for opinions & you got mine.
And I'm an AF Security Police vet & retired career cop.
There would be no options if the gun were here. Aside from making sure it remains functional, I wouldn't do a thing to that finish beyond oiling the gun occasionally against rust internally.
