So yeah, I purchased a typewriter from a gentleman on Craigslist a few nights ago. It’s a Royal HHE, c. 1956, and it works quite well.
However, some of the typebars had so much gunk that the output looked just horrible:
I now have two sketches in my Moleskine sketchbook. Both are maps. One’s of The Highlands, done a couple years ago; the other’s of Smoketown, done more recently.
