Sylvania question...

Inspected this Sylvania split bus panel this morning. Home was built in the 50’s. Panel was pretty full, and I’m not sure if this one had the copper or aluminum bus bars. Any sparkies recognize this, that can tell me if this is one with the concern or not? (Yes I saw the double taps, but other issues noticed would be appreciated.)

I’m not a “sparkie,” but that’s just a Zinsco with a Sylvania sticker on it, which dates it to the around the '70’s or later. Which also means, it has AL bus bars.

That will do. Thanks Jeff!
