G-10, I think it is a Kurfurst looking at the canopy but I could be wrong. I know the model all over the net you are referring too but I am skeptical of it being a 'green' 5. I'm thinking maybe it's more of a blue perhaps? And the red border on the retored logo of the profile shot on the web may or may not be red either.
I chose a green border because of my restoration process that I do. If you squint you'll see a slight border around this emblem. So, basically I imported this image in PS CS6 (x64) then on another layer I painted spots around the border all the colors of the rainbow (red, orange, yellow, green, blue, purple). Then I did image>mode>grayscale and observed the change. Then I looked for which of those colors turned into a shade of grey that almost blends in with the color I picked with the 'color picker tool. I more or less painted a spot over lapping the spots on top of all the colors I changed and then which ever one was closest I varied the saturation and shade and repeat the process several times until the color disappears into the spot I painted with the original gray portion I picked (I may host a YouTube video of this).
