What is this for?

[Robert Jones]

Home built in 1957, 125 amp Zinsco panel and this box next to it. What are these for?

That was a Square D fuse box, but it has been converted to house that transformer. There are 7 or 8 low voltage circuits heading off to different places, so my guess would be low voltage light switches. Were the light switches odd-looking?

All of the light switches were the older "push" type...

If they were for the switch loops, then where were the relays that they'd control? Or might the lighting circuits themselves have been low voltage?

It's certainly a curiosity.

Antique alarm system? Thermostats? Toy trains in the attic?

When you say "push" type, do you mean rocker switches like any of these?

If yes, then I would be pretty sure it's a low voltage switching system transformer.

If they were for the switch loops, then where were the relays that they'd control?

I've seen quite a few systems that have the relays attached to the individual fixtures.

Maybe that's not a transformer. Looks like they are red and green wires for telephone use. Maybe this is the demarcation point for telco.

Well, it's definitely a transformer, but telephones need to have step-down transformers to work so it could be for a phone system.
