The Zenith 12H090 I just completed has both FM bands, and that set was from 1947 (earlier variants go back to 1946).
There is quite a story behind FM, and the competition as it was introduced, rejected by RCA, and E.H. Armstrong attempting to strike out with his own radio network. If you ever get the chance to watch the Ken Burns documentary "Empire of the Air", it tells the story rather well and is well worth viewing for lots of other radio history.
I don't hold with furniture that talks.
