For a first 1860 Colt black powder revolver you would be miles ahead of the game if you bought the one that Cabelas has on sale for $199.99 and take the finish down to bare metal for the look you desire. For $4.00 more than the kit price you get a gun that is completely assembled and is guaranteed to work with a no quibble return policy. When you determine the gun's function and fit suit you, you can strip the finish down to bare metal which is the look you want. Total time invested maybe 5 hrs. tops. You buy a kit and you are on your own as far as putting it together and there is no guarantee on it. If you screw up, you are on your own. I don't know how skilled you are as far as mechanical assembly and finish but I know from personal experience it is not a cake walk. Years ago I bought a single shot percussion cap pistol kit for $29.95. I being in my early, early 20"s I got the gun together so it functioned ok but as far as finish it looked like a rough cut 2x4. I wanted to get it working and I figured to do the finish work later. It never happened and years later I sold it for what I paid for it. I guess what I am saying unless you have the skills and discipline to see it completely through you would be better off and money ahead buying the completed gun and doing the finish to suite your tastes. Not trying to rain on your parade but just trying to point out the pitfalls.
