This antique Corona typewriter looks to be complete and is in more-or-less working condition. A good cleaning and lube couldn’t hurt but all keys operating as they should, of course, but I'm assuming it will function as it should with a little servicing and just need a fresh ribbon.
As far as cosmetic condition goes, the typewriter show minimal wear from use, but I don't see any signs of abuse or damage. The paint is worn in some areas and hopefully the photos will show that. Beyond that, the chrome looks pretty good and there isn't any damaging corrosion or similar issues that I can see.
