Okay I found the box with switches.
I have two switches. Bad news I only have one knob.
I also only have a black bezel for it.
The switch in the photo with the knob and chrome bezel is for one of my cars.
Turns out there are at least 4 styles of switches. One pull and three push. The earliest push is also in the photo.
The switch that is available is at the top of this photo.
Send me a PM if interested.
