Alex over at Flourite was very very helpful. We will due a spectrograph on the Stauat sometime soon.
I have learned flatting base will not take the paint below satin in gloss and special powders only available at factories needs to be used if opacity and gloss is to be controlled.
They have offered to flat down the samples I have to hand. They have done a number of Khakis for vehicles and I discovered the sample I had done earlier by R&D was done by them but to a modern colour because the sample I provided was not passed on. OHHh the things you find out...
Confirmation the Greens and Browns manufactured during the war and later contained Lead and that is now illegal to use. The Lead was not only a preservative and anti corrosion agent it was the colouring pigment .

http://en.wikipedia.org/wiki/Lead(II,IV)_oxide
Because of the reflective properties of those pigments Vs modern pigment all modern reproductions will look different to the original in different lighting conditions.
So I have to settle on not only a time in history for the colours but also a time of year and time of day ... So winter ( june July) and Noon ???
then this arrrrrrggggggggg

The quest for perfection is ,consequently, a hopeless cause.
