They might be finally replacing it all this summer, most likely with a Notifier voice-evac system. The system was REALLY loud, not surprisingly. It’s at my middle school built that year with an old Gamewell DurAlarm system with flush-mount Federal Signal explosion-proof horns and Gamewell Vitaguard dual-action pulls (1920s-style doors.) I know part of the building was remodeled after a fire in the late 80s, and they put in newer-style Federal Vibratone 350 horns and a Gamewell Century pull. Speaking of the year 1957, that’s the year the oldest system I’ve seen in operation was installed. I have seen a system like that in a school originally built in 1957 with an old Edwards system, then added into in 1973, when a Simplex 4208 replaced the Edwards panel, and the old Edwards alarms were replaced with Simplex 4051+4050-80s, but they kept the Edwards 270-SPO pulls in the original 1957 structure. Never saw the panel but its either an Edwards one from when they upgraded the system in the 1970s or a 4208. Simplex 4051 horns on 4050-80 flashers in continuous with Edwards SPO pull stations. Probably my middle school which at least for the time being still has its system in place.
