Radiomuseum.org lists five models from Wipple-Raine, all from 1925 and 1926. These are all battery-powered TRF sets. Does the power transformer appear to be a factory-installed unit, or does it appear to be part of an aftermarket/homebrew battery-eliminator power supply? My guess is that it is the latter, since sets with integrated AC power supplies didn't become common until the very late 1920's, when radios finally ceased being marketed as mysterious hobbyist gadgets and became sold as "user friendly" household appliances that any non-technical person could enjoy.
In any event, if you know what sort of tubes it uses, you can figure out the voltage requirements. For a typical mid-20's TRF set, a power supply (battery eliminator) needed to generate three independent voltages: 45-90VDC at 100 milliamps for the plate circuits, a few volts at several amps AC or DC for the RF amp/detector/audio amp tube filaments, and a separate low-voltage AC circuit (at a few amps)for the rectifier tube filament.
