“Typewriters depended on how hard you mashed the key to determine the darkness of the print.”
Do they tilt too? See the “K” in Wichita, Kansas.
The K’s in Kapiolani, Kenya and Kalanianaole are all tilted in the same direction. The height error in Kansas can be caused by typing too fast if the typebars get jammed. It would also cause a lighter print to appear.
