Nice link. With some data I have not previously seen. I am beginning to seriously doubt some of my other sources. 
It would be a brave fellow to suggest Milos Vestik got  it wrong.
I think we can definately add 
White tips to to the props
White roots to  the props
White front to the cowl rim.
and for the sake of accuracy I think we had better (and I say this reluctantly) rename the thread "off white 01".
(which is particularly annoying because I could have used your original colour pallette for that  

)
great work as always Greebo
