Compare post photo of original $2500 Colt with this, the Colt 01918 reproduced for less than half the cost (at least when they were marketed--don't know if they still produce them).
Black oxide finish.
I do not, incidentally, want to appear to be bashing your friend's pistol. I am only commenting on what I thnk I see at that photo's angle, and I am only an informed amateur
From the photo (the $2500 one) my feelings (based on my eyes) are it's the 01918 Colt made recently.
