Lots of original finish is certainly desirable,but there are a lot of high dollar and eagerly sought after Winchesters and Colts that don't have 70% finish left.They do have original condition and sought after factory options.Rarity trumps condition for many collectors.One of the nicest doubles I ever saw was a B grade Lefever 10 guage with about 50% case color and beautiful patina on the barrels and stock.That was over 35 years ago and I wish I had had the $300 dollars the guy wanted for it.
