Unfortunately that is without a doubt refinished, and not by Colt. Someone was over zelous and very heavy handed when they did the job of polishing. Value would be tough, I beleive originality is key with any Colt and in this condition it would be the market that sets price. By market I mean if you put this up on one of the auction sites and started it at a penny with no reserve you could get the auction frenzy going and maybe get up to ????. No matter the extreme of condition, honest use and wear looks the most appealing to me. Although some folks just want a century old shooter that is affordable and this might fit that bill. If you like it and it functions and throws lead down range then shoot it and have a good time!
