Those "snakes" are highly sought after because they don't make them anymore.
I have long suspected that if Colt was to start making them again, it would just drive the price of the older ones higher. There would be "original or "real" Pythons" and "those new ones." The people who want one now, would still look for the older ones.
You can still get a Model 27 from Smith & Wesson I believe, or at least you could not too long ago, but they don't sell many I don't believe. In the meantime the demand, and the prices, for the older guns just keeps rising.
For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have everlasting life.
John 3:16 (NKJV)
