If you’re working at getting the little ones started into typewriters (or just starting out yourself), Mr. Rogers covers some of the basics in episode 1083 of Mister Rogers’ Neighborhood from February 25, 1970.
You can see Mister Rogers demonstrate the use of what appears to be a Royal Futura 800 in the full episode here: https://misterrogers.org/episodes/typewriters/
“I was very much interested in letters.”
—Fred Rogers
While he used a Futura in the show, his personal typewriters included a 1930’s Royal portable (possibly a Model O?) and a Royal KMG, which can be visited at the Fred Rogers Institute by joining the 143 Club.

And if you’re a serious fan, you’ll potentially have a Royal KMG and Futura of your own.
Nice
My first guess was Adler from the coloration. And the ribbon cover looks rounder than the Futura to me.
