If you go to RadioMuseum and type 101.482 in the simple search box, you'll see there are 3 radios that used that chassis, the 4789 console and 2 table radios.  My impression is they're not terribly uncommon radios.

However, you would need the knobs, the escutcheons, the speaker, the grill cloth AND the chassis.  The console speaker is likely larger than the table-model speaker; if there's a part specific to the console, the speaker would be it.  To find all those altogether, you're likely buying a whole radio, in which case you get a cabinet too.

If you already had a complete one with the cabinet damaged beyond repair, that would be one thing.  But buying just the cabinet, and hoping some day one with a downer cabinet would materialize, that's a different thing.  I know a guy who had a pristine, original Stromberg-Carlson 635 chassis, and it took him 17 years to find a pristine, original cabinet. And that's a model that comes up on eBay once or twice a month!  It may be worth it if it was factory-mint like his.  But such is not the case here...
