Dfariswheel,
You're quite right about the polishing providing that beautiful shine. However I'm told by two competent gunsmiths that the blueing salts & solutions used by Colt are very difficult to duplicate which accounts for the difference in the color between Colt and the other gun makers. Colts have always had a slightly different, some say "bluer" color, than S&W and Ruger.
Lunde - Sweet! Send me a PM, we're in the same area and I'd like to know where you found that little gem! Also, you might try taking some photos of your Python on a red or emerald green (felt) background to contrast with the blueing. I'm also interested in talking to you about gun photo techniques. Yours are outstanding (as good as DHart's nice work!).
