We have a bunch of them in my area. You can still get breakers, I believe they're Siemens now. I hate the dern panels. the neutrals were behind the breaker screws. Cost me a few screwdrivers and a few gray hairs. They were also very susceptible to humidity in basements and definitely were not good for SWD duty. The ratchet mechanism in the breakers seemed to quit a lot sooner than most. I can't count the number of breakers I replaced that just wouldn't hold, even with no load.
