[TR] TR3 Ashtray question

[Carl TR]

>From the TRA judging guide:

After TS 42400, the optional swing-away ashtray was replaced by a standard
unit that slid outward on a bracket fastened to the passenger's side dash
support stay. The mounting bracket was painted gloss black. The body of the
ashtray and the tensioning spring were clear cadmium plated. The rectangular
face plate was black bakelite.


The question - what should be the finish of the inside of the tray?   The one
I have is black - but should it be 'cad plated' the same as the outside of the
body?

Thanks
Carl
