late RP Standard and De Luxe / Stock Colours / definition of "black top"

[Reckless Rat]

With the caveat that a customer could order his car painted any colour scheme he liked, outwith the basic catalogue, for a fee of course.

My "Standard" saloon is black top (and bonnet) with  maroon and was like that when I bought it in the 1980s. No doubt, repainted by a former owner but it looks fine to me.
