One was a Smith Corona Classic -- big and heavy, for all that it is a portable, and mustard-colored. The second was a more compact Smith Corona Galaxie II, grey and ivory with a tidy footprint and responsive strike action. I gave the Classic to a friend who, mirabile dictu, was herself inspired to type letters once again.
The story does not end, however. My in-laws, hearing of my interest, sent to me their electric Smith-Corona. Also dark grey. She reminds me of a Star Fleet shuttle craft (the TNG not TOS version). Which makes me think that ner name is likely to be Galileo. (The Dart has been named Mouse.)
