Notice the speedometer goes to a different colour marking at 80km/h and higher so what country were these originally designed for???
The faded orange sections used to be red years ago, and yes they can be refurbished.
On these faces the face plate is actually a green coloured plastic onto which blue has been sprayed to the face and white and red sprayed only to the raised markings.
When illuminated at night, light shines through the markings only, simply because the white and red areas are thinly sprayed, something the aluminum plate faces cannot do.
Now i know why the temperature gauge faces for these years of face had this feature carried over for a few years before they went to a printed aluminum plate design.
