I went into a little second hand store yesterday. Sitting in one of the display cases is an original 1849 colt .31 caliber revolver, with an asking price of $550. I would have immediately snatched it up at that price except for one thing. The owner of this beautiful piece of history, had taken it upon himself to "clean and polish" it, as in he took it to a buffing wheel and polished the living daylights out of it, so the brass grip frame was nice and shiny yelllow and the rest of the Gun was buffed down to bare steel. I handled it, shook my head and left. Sadly many people don't realize that the 2 things you never polish are antique firearms and coins.
