It's probably a subtle difference, but is this machine provide the standard 6 lines per vertical inch or due to the taller ascenders/descenders is it a 4 lines per vertical inch machine?
If you need a "name" for this machine, I might suggest "Satchmo". In doing some research on Louis Armstrong's 5 series Smith Corona, I'm pretty sure his 5 series also had this same vertical script. None of the features on any of the photos I could find of his machine are subtle enough to distinguish which particular model of Smith-Corona he was using. If we find a good direct photo of the machine itself, I'm sure I could puzzle out which version he used. By 1955 he had at least one machine with a script face (see: https://www.louisarmstronghouse.org/virtual-exhibits/my-fifty-fifth-birthday-celebration-happy-birthday-louis-armstrong/). It doesn't appear to be Smith-Corona's common Script (Artistic) No. 75 , but more like Script No. 46. Based on a version of this photo (https://www.usatoday.com/gcdn/presto/2019/07/15/USAT/d815dddc-c0b8-4c54-b9b5-719886d4a0cc-02_Armstrong_Louis_16.jpg?width=1292&height=1320&fit=crop&format=pjpg&auto=webp) it would seem that it's the Smith-Corona that was the script machine (as opposed to his earlier Remington).
According to Ted Munk's post on the S-C Vertical script: "Smith Corona is offering the [vertical] typeface as 'Script No. 46', 10 Pitch by 1954."

Somewhat interesting that Louis Armstrong played cornet, wrote on a Smith-Corona, and lived in the Corona neighborhood of Queens, NY.
