Outside of compiling articles from the older gun magazines extolling their looks and how they contributed barrels to be made into 'Smolts' and 'Coogers' for PPC - along with a few appearances in movies and crime novels, that void will keep on needing to be filled.
Apparently, there's no 'fascinating history' attached beyond their being currently in vogue and out of production.
Their histories are on the thin side, since they never 'did' anything historical like the Single Action Army and Government Models did - they weren't used for magnum cartridge development like the large-frame Smith & Wessons were, they were almost too expensive for cops, and came along almost too late on the target/combat scene before being overtaken by more popular autos.
The distinguishing points of the Pythons are fit and finish, and they were Colt's eventual answer to S&W's Registered Magnum - hand-fitted, high-polished and super-smooth - the epitome' of revolver manufacturing as done by the boys at Hartford.
