Cletis, it may have misspoke. After I wrote that, I found another link on a search that indicated that these were an option. It could have been purchased as an option, or added later. I'll never know.
I have a 1953 3100.
All I know is that I like them, and want to refurb them. So, I'm looking for any diagrams that I can find.
