The issue isn't the raised "th", but the fact that the "th" is written in a
smaller font as well.

From 1968 on SMC (Smith Corona) typewriters had two optional keyface
slots (shift one and shift +) for a number of optional letters, accents
and marks. I had section and paragraph marks on mine as I clerked in a
law office. "rd" and "nd" superscripts were also available.

Did they also offer proportional spacing and intercharacter kerning?
