You beat me to it!
110/220 volts DC was very common in the Downtown Elevator districts in large cities. Some of the buildings were residential and the living areas were equipped with DC circuits. Many of the units had gas refrigerators, as electric refrigerators weren't made for DC, unless they were the Ammonia type, like gas refrigerators.
The Emerson distributor, that was north of the Milwaukee downtown area sold a lot of them and the tech that worked there said they still get them in for repair. That was in the mid-to-later 60's.
