Aussie WW2 staff cars

[Mike Cecil]

"According to the “good book”, cars of General Officers were to be coloured black and carry a Commonwealth number plate front and rear."

I wonder what 'good book' the late Mr Wright was referring to.

Ministerial cars ie the Commonwealth Govt fleet for senior govt and Departmental heads, were black with C plates. I don't remember seeing any wartime instruction that cars assigned to senior officers were to be black, but I'd certainly be interested to see 'the good book' to correct/change my understanding of that.
