"Patina" is in my opinion over-rated. My prior hobby was vintage cars, they cost several times what a 1941 Colt costs and honestly? It's pretty hard to convince a collector in cars that "patina" is best. We put up with patina in old firearms. Some people think that's how an old gun is supposed to look and that's fine but compared to the original finish it's a sad substitute. People also say "its original only once", and yes that's true but unless the firearm came that way, patina is not original either.
