That Model D had  magnificent typefaces; it was proportionally-spaced.
The space bar was split in the center--one side gave you an "em" space
(wide); the other gave you an "n" space (narrow).   When backspacing to
correct, it was a bit of a mental trick to remember how wide each
character was.

Mine had the Arcadia typeface.

It goes almost without mentioning that one used a film ribbon with these.
