I went to the big Seattle Goodwill, and found one of the last Smith-Corona manual portable typewriters made, a Smith-Corona Classic 12 Correction/Typewriter. When I transferred buses, the case fell open, and out fell the Smith-Corona. After popping the ribbon cover back into place, I noticed that only 2 parts had been broken--the plastic margin stop toppers!
The very last manual Smith-Corona typewriter was produced on May 11, 1983↧
