What Damasus pattern do you like best?

This is the 16. I don't want to mess with the rest of it, but I would like to restore the color to the bbls.

My 1907 GH has barrels marked 'D3'. In my limited experience, I noted that the number next to the 'D' was the same as the number grade of the gun, thus, my GH should have had 'D2' barrels. Is that how the system worked, or am I reading too far into it?
