Repair Wiring for Tandem Stack Switches

How to Wire a Tandem or Double Switch

Repair Wiring for a Tandem Double Light Switch

Electrical Question: I have a light in our foyer controlled by 3 switches. Any one can turn the light on and off.
The switch by the front door also controls the ceiling fan. It is broken. It is a vertical with two toggles that flip horizontally.
The switch appears to be old school. The insides don’t match the switches I have been sold. None of the replacements work. The fan runs with the light on no matter what. The other two switches stop working entirely. Any thoughts on getting an old school switch like this? There is no part number or any id number on it. On the old switch, right side, top to bottom it was white, red, and black wires. On the left top to bottom it was black and black.
Thanks for any input or opinions.
