What I love about typewriters is you have to own your mistakes. You either X them out or start over, but you have to own it, learn from it, and move forward. No one or no thing will autocorrect it for you.



RESEARCH NOTE: When researching the Royal KMM on a computer with lots of screen real estate, you may find that launching the Royal Serial Number page and the Royal KMM By Model/Year/Serial page in new browser windows can give you interesting perspectives on changes throughout the model series.
