In reply to Jessica.

Jessica, you can do some internet research to see if there are any photos of him with a typewriter which we can use to identify a make and model. However, his letter in the video is so clean, crisp and even that I'm almost certain that it was printed from a computer in a courier-style font that makes it look typewritten. (Most screenwriters still use this font for printing their scripts.) Some of us are collecting photo examples of writers and their typewriters (preferably working together), so if you find one, let me know. Richard Polt keeps a current repository on his website at https://site.xavier.edu/polt/typewriters/typers.html.
