That looks just like my peacock 10E - what I think green would look like with a bit of blue tint.
Looking through several parts of Greenburg's book, I see several shades of peacock including some more green than blue.
None of my references mention green for a 10E except for the dark green frame.
That dark green is something else. I had always thought that my 10E had a black frame, but recently I saw mention of the dark green.. Looking very carefully at mine next to known black, I could see the green. I have some GG-1's that present the same problem. They are very dark green, but from several feet away or in poor light they look black
