That is a Superb Colt Police revolver. I like it myself, even with the polishing!
It is a shame someone did polish this revolver, i do not see any area that has any rust pits that would makew someone remove rust. But just wait for another 100 years, and it will look original again, LOL!
Well got me another one, havent got it home yet tough, but its on the way..
Here are some pics i downloaded from the seller, this one is not polished
I'll post some of my own pics when i get it in my hands
