It is three tone I shall explain.
What we have is a combination of these two profiles so to speak.

Photo in question.

Now is every one agreement that every thing below the red lines is gloss black & above the standard PR blue? Now the nose at least to me looks gloss black right across the nose in front of the cockpit. So some place near the cockpit & past the leading edge of the wing & behind the engine of the plane there is a demarcation line we can't see.

I won't use the second picture as it has not got enough detail to tell for sure what we are looking at.
So lets focus on demarcation lines and the tail shall we.


See any similarity's with the profile & the photo?


To me there is two clear demarcation lines near the tail & at least three different colours converging at the tail.
