modification described here. I decided to make the scale transparent.
First I designed the new scale. I has the same layout and proportions as the original black scale. Then I printed the image on a matt polyester foil on the common desktop laser printer.

Diameter: 4.8 mm
Color: yellow (590nm)
250mcd @ 20mA

scale itself replaced:
replacement finished, right before the front face with
the smoked glass is attached.
