A Pony die-stamp. That's it.
Do you have any idea what that thing is worth?! If small, no-capital type companies such as Freedom Arms can manufacture fine revolvers and sell them at high prices, so could Colt. Sure, they gotta buy new machines, but there's no reason they can't make a "copy" of a Python and sell it easily for $999. I'd bet a ton of money they would be very hard to find on the shelves until Colt could up their production.
Take Smith and Wesson, for example. They have changed ownership a few times. The magnificent revolvers they produced, say, 50 years ago, are nothing like the crap they sell today. New owners, new parts, new construction methods. People still buy 'em just because of the S&W stamp.
And, they still make SAA's, don't they? How is making them any more cost effective than making at least 1 DA gun?
Personally, I don't care, I'm not a huge Colt fan, and I probably wouldn't buy one. But the business man in me says there's a lot of bad management over there.
