Mine, all mine -- except for the ammunition; that's from Tam's collection -- the Colt Police Positive Special:Alas, it needs a new ratchet, the widget at the center of the extractor star that the hand* reaches out and moves to advance the cylinder for the next shot: one or two teeth are iffy and a third doesn't talk to the hand at all. (It seems I need to clarify this. It's nothing subtle, not the width of the teeth or the slope, it's that three of them have been worn, filed or beaten too short. Failure mode is that the reaching hand moves out...and doesn't engage at all. Two of them will sometimes actually engage, the third never. How one beats up a part so rarely exposed is a question to which I have no answer.)
Mind you, when it does work, it's a fine reminder of why a 20th-Century Colt revolver is a thing of beauty and joy forever, just as smooth as can be. The .32-20 cartridge, originally in black powder and intended for a small-game rifle (rabbits and such), is pleasant to shoot and modern smokless loadings are hotter than .32 ACP, roughly equivalent to the amped-up .32 Magnum/.327 pistol loads.
No luck on parts so far -- came up empty at Numrich. I need to find out if Jack First might have the part.
* Yes, it's called a "hand." Always looked more like a finger to me but I suppose the magical imp that lives inside revolvers and works all the levers might need a whole hand to advance the cylinder. Magic imp? -- C'mon, you've seen the drawings, there's way too many parts in there for it to work without one.
