We are tempted to use the term 'museum quality'. But, if you'll notice, museums have mostly used items. What makes them suitable for a museum is who used them, rarity or to illustrate a historical period. Consequently, museum items are shown with all wear, scars and patina intact because in that way you have a direct connection to the users of the past. It is actually more difficult to maintain such an item than one in new condition, especially things that rust. Nothing against the beautiful Colt! I'd love to have one, but I just don't love it enough to drop $5000 or whatever it takes. I would touch it and show it. I would take it apart and oil it. Over time, it would begin to show wear and discoloration from oxidized oil. I much prefer an obviously used one that was actually used in the great wars of the 20th century. I know I am going to touch it and oil it, so this way I won't mess up a new one and be kicking my own butt for the rest of my life. At least, I have progressed from the time when I had to make old stuff look new again. :)
Nothing like a nice old gun with patina from many hands down through the years - especially if it came down through your family..
