Jackwrite Serif Font has it that Jack Daw used a portable proportional typewriter on the road; handcrafted from parts of other typewriters. This font mimics how its output maybe was.

Technically Jackwrite uses 92 types, each in 9 variations, from Fredrick Brennan’s hyperrealistic, multilingual typewriter font TT2020 and turns them into a proportional font by definings spaces (kerning) between each type pair.
