I have two manual typewriters, one is a Olympia SM3 Deluxe with tabs, paper shield and paper supporting paper bail portable in brown, and the other is a very rare full size Royal Olympia with telegraphers type face with all capitals and slashed zero.
My "DREAM" typewriter is a portable Olympia with Italic Large and Small capitals with a slashed zero. The owner of Vibroplex in New York had one - he ran a typewriter repair and telegraph supply store so he sold both - he used the Italic Large and Small caps manual typewriter for general correspondence as well as copying telegram messages. At one time retirees from Western Union and Press Wireless had a private wire running from Philadelphia, PA through New York to Hartford, Connecticut - with a few dozen subscribers who were WU and AT&T and PreWi retirees.

When standard manual MILL typewriters became rare, I ordered for my ships an IBM Selectric and an ORATOR typeball which was small and large caps, no lower case.
