That's deserving of a strip, prep, and fresh coat of black paint. Here's one I've had since the mid 1960's and it was used when I got it, from a funeral home where it was used to keep the Cadillacs ready for the recently-departed and their mourners. Probably 40 years ago, I blasted it and rattle-canned it, and it's held-up well. I have a Deltran charger/booster with Li-ion capacity I now use, but if this needs to, it does the job. I'd say it's 55+ years old.
One of my Deltran chargers took a dump, so I cut the cord, and they sent me a new one, but my Schauer is still working.

Ford had an earlier pushbutton system, in the steering wheel.
