Just noticed, these are 120 volt panels (see main knife switch handle in first post), so the neutral is both fused and switched?
Often done on those older services. Even just two 30a plug fuses fed older homes with 120v.

Also, for many years, there was no consistency about whether one conductor was grounded.

Nice find!
120V panel with double pole switches and both the line and neutral fused. I wonder if they even grounded one line?

Also looks like a lot of 30A fuses for a 60A panel. I'd guess this probably started life full of 15A fuses, and someone got tired of replacing them as more newer appliances were added.
Its from the 110V DC service days.
In the 1911 NEC lighting branch circuits were limited to 6 amps or 660W @ 110V. Unless you had fuesd rosetts. My guess is there would have been no neutral or grounded conductor . Just two ungrounded 110VDC lines. The code did have 55/110 multi wire systems and would have allowed 12A fuses @ 55VDC.
We still have some 120V service around here in old apartment houses, not in that nice of shape.
If its pre electrical grid it could have been used on a 32VDC delco generator.
