The ordering paperwork would be needed.
Maybe that's a prior year color? what you've shown is fairly pale and the pre 69 colors always seem that way to me.

For instance C Medium Blue is a 68 color. Just a thought.

Thanks for that picture! It seems some colors are a mystery as they were Imperial/C body only.

You got any pics of R8, T8, A9, F9, M9 cars?
