This machine lacks a paper support arm. The metal piece to which it would attach is there and intact. So, perhaps it fell off.
Status: Typewriter Hunter
I have collected typewriters since the early 1970s. My first collectible machine was a Mignon, but I also had everyday typers then, first a Voss ST-24 and an Olivetti Praxis 48, and then a Hermes 3000 and a Hermes 10. Over the last decade or so, I've turned my focus from early machines (Lambert, Blickensderfer, Hammond, Smith-Premier, etc.) to portables.
Besides typewriters, I also am avid about Studebakers, and have had a 1964 Studebaker GT Hawk since 1979.
