... It is a VERY old and rare house electrical service that has only 120V.
Ah, so there was historically something like I described then?
Indeed, some rural areas had service at a price fixed per light bulb. In the city, some buildings were originally lit by Edison's 100VDC system, and these were originally converted by simply hooking up to (Then standard) 110VAC when the local DC generators were decommissioned. (Due to line resistance, the voltage at the DC generator terminals was usually 110-120V or so.)
You can still find some old 110VDC fans around in the antique shops!

I was thinking more like 1950s era, and using small overhead pole transformers.
