Based on my trio of Stromberg-Carlson consoles, band coverage "progression" 1946-48 for these models; 1121, 1210PLM, 1409PGM.
A prewar (1942 m.y.) S-C model 430 offered BC, full SW coverage (5.8-18 MC) and first FM band of 40-44 MC.
The 1121PLW has just the old 42-50 mc band for FM (ukw) plus a bit of SW 8-10 mc in addition to the AM (mw) band.
The 1210PLM has both the old 42-50 mc and new 88-108 MC band for FM (ukw) plus just the AM (mw) band. The FM dials were listed by channel numbers, not frequency. old fm 20-100 new FM 200-300
The 1409PGM has just AM and FM using the 88-108 numbering. This model was known for its lighted tone controls, possibly due to need for more control of sound equalization with FM ?
Shortwave bands were dropped from many sets by 1948, when FM was becoming established. HiFi era was still 8 years away, when FM band would get much more attention from design engineers.
I only recently discovered that Canada did not have FM until the 1990s. Assumed to be too distance-limited for such distances and vast wilderness?
