The ones you have in the photo look like a good mix. Perhaps one even earlier model, and either an Olympia or an Olivetti Studio 44 / Underwood 21, if possible.

I would like variety. A series of typewriters were set up QWERTYFest recently, and I was disappointed that they were almost exclusively manuals from the late 60s to 70s, and most of them felt about the same when used.
