I believe the Colt Border Patrol revolver only came in Blue or Bright Nickel. Maybe the one you've got the Nickel plating has or was diminished to the point it appears to be Brushed Nickel or it was refinished that way. Anyway, I also don't believe Colt is currently doing any re-plating work currently so you may need to look at some other firearm refinishing sources. If your gun was original Bright Nickel I'd recommend that you go back to that since Colt only made a small percentage of the Border Patrol's in Nickel. Good Luck.
