I think it's kind of crazy, but the insurance companies are giving my mom who's in her '70s a difficult time renewing her insurance. The latest ask is that we provide the full make and model of the electrical service panel. It was installed around 1990 and the paper inside showing the make and model and diagram is missing.
The main breaker is 125 amp Challenger Type C 2125 so I think that likely means it's a Challenger panel. I have no clue how to tell them the model number if it even is a Challenger panel. As best I can tell they went out of business and we're bought by Siemens or somebody else.
There is a UL label at the back:
