D24 Clock Question/Observation

[windsor8]

Working on my Dodge winter to do list. One thing on it is to refit the clock with a battery quarts works since I have gone to a 12 volt system. Don't worry I didn't molest my nice original clock. I got a parts clock to do the conversion on.

Something I was wondering about when I got the parts clock apart was why it was painted green inside? I was also amazed at the detail in the old clock and its brass movement.

It is probably zinc chromate primer, it protects aluminum from corrosion.

I think the green coloring is so the instruments will have a soft green glow at night. The bulbs aren't tinted in the instruments.
