You can backup your original Opart 3 fonts.ini and start right away with experiments..why not?
Be it as it is, the most common fonts all in one picture:
Note that i don't use the deafult font for the Place Name Fonts but that i kept the standard sizes/colours to stay in "sync" with the conventional use.
All other fonts that are not displayed on the screenshot should be self-explaining. Document Font, Small Supply Font, Objective Font, Tool Tip Font.
Medium Font is also used in the Battle Report and all other info screens (Theatre Options, Replacements, Air Briefing, Situation Briefing etc pp)
Just note that if you want to see those SS Runes, you need to use the bitmapped fonts for the Small and Medium Fonts (and a couple of others - I forget their names).
