I'm curious what the sourcing is on your differentiation of the two models? Are there manuals, advertising, or other details to back up the differences? From what I can see, the phrase "Rhythm Touch" seems to have been an advertising tag for the Underwood SS which started a few months after production of the SS began and there wasn't any difference in them other than the advertising tag.
Robert Messenger has some scant history on the machine and the differences, primarily due to a redesign at the time, at https://oztypewriter.blogspot.com/2012/11/on-this-day-in-typewriter-history_25.html. The primary change from the S to the SS seems to have been a move from a carriage shift to a basket shift and so it seems somewhat fitting that Underwood uses the phrase "Rhythm Touch" as an advertising gimmick much like Smith-Corona were doing with their "Floating Shift" marketing.
Generally standards at the time were not differentiated by different trim lines as standards had all the bells and whistles for office use (potentially aside from custom use cases like decimal tabulators or extra wide carriage). Meanwhile all the trim variations were generally seen in the portable market geared toward home use rather than office. This would seem to support the idea that there's only the SS and "Rhythm Touch" is only an advertising tag line as the SS was newly introduced in January of '46 and "Rhythm Touch" appears around July '46.
There's also some discussion on the TWdB in the commentary at https://typewriterdatabase.com/1950-underwood-ss.23202.typewriter which may add to the question.
I'm curious to hear everyone's thoughts on the idea/thesis that the only model is the Underwood SS which is being marketed as the "Rhythm Touch" or evidence to the contrary to refute the claim.

Fans’ strong emotional connection to their idols and heroes means they are often predisposed to believe them and trust their messages. This trust disarms fans in the face of mis- and disinformation spread by the celebrities and influencers they follow, nudging them to research and possibly repeat false narratives.
In my personal opinion, I do not believe we should be so surprised at the fact that influencers have such a power. They push propaganda out one way or another on a constant basis. In fact, it was my goal to to get sponsors for our podcast which meant that I would be paid to read advertisements on each episode. I would be directly influencing my audience to purchase a product and possibly be placed in a contractual agreement to only say good things about said product. If celebrities can push skin care products onto their fans, how could we not see them trying to convince their fans that a vaccine will cause bodily harm in the long-term. They built a trust that cannot be broken unless their audience can be skeptical enough to not take the bait. Influencers need to be aware of the impact they have on their audience and need to do their parts in ensuring that all information they share is validated and confirmed by trusted sources.
