This conversation had me paying attention to some of the battery sets in the early Sam's from Halser that I've been sorting in to my cabinets to fill out missing sets in my Sam's collection.
I found that RF stage Silvertone I used to have in the Sam's is a 6220 (and that nostalgia air has the riders for it).

A good set to exemplify the rural electrification going on post war is the Zenith 6G038...A radio with an identity crisis. A big multiband wood table radio, with an antenna that looks like it was borrowed from the Transoceanic poking through the wood top with a nice 5 battery tube circuit and a 117Z6 as a 6th tube so it could run off battery or line voltage like a 3 way portable. In addition to assuaging fears farmers would have of a battery radio being obsolete when power came, it probably also was popular with folks that spent half their year in town and the other half off grid.
