13 Points, Typewriter Hunter

I am a mechanical engineer, who likes vintage mechanical things, especially mechanical clocks and weather instruments. As a kid in the early 1980s, I had an old Sears manual typewriter that my mother let me use and had good memories of. Just a few days ago, I got my first typewriter, a Corona Junior (1937), and am hooked. I'm looking at other ones but my wife has her foot on the brakes!
