The Royal Companion was a trim line name for Royal portables in the 40s and 50s along with variations like the Aristocrat and the Quiet De Luxe. For some of its life it's essentially a cheaper Quiet De Luxe which may be missing features like a tabulator, Magic Margins, card fingers, or a touch control. You'd have to cross check the manual and the typewriter database to see how yours may differ from the QDL at the time it was made. Often it was a $5-10 price differential at the time for the difference in features, but with inflation this would be the equivalent of $140 now.
You could essentially use the list of QDL users from Polt's site and say that they all used a typewriter similar to your Companion. (Depending on the photos and angles, some of the listed Quiet De Luxe users may have really been using either a Companion or an Aristocrat, but it's incredibly difficult to discern unless you can see the specific feature differences between them.)
