Much though I loved the original man from U.N.C.L.E. they didn't actually have access to significantly better electric typewriters than the rest of us. Ritchie and his professional typists used commodity typing machines, with the interchange of fonts, and mechanical positioning capability of the best of breed in market at the time.

If you needed to forge russian or german papers, you used second hand russian typewriters. They were available. the NSA didn't have magic 1200dpi+ printing any more than anyone else did in the time of phototypesetting: the magic here was how good the lenses and film were. Type foundries did the best they could with large images and then reduced them onto film.

Scientific papers right up to the 1980s accepted hand drawn images: I know because I submitted some, for state-event flow diagrams on an OSI protocol implementation. They published my hand drawn circles and lines.

What's the source of that? It's not mentioned on his Wikipedia page and Google was next to useless trying to find anything.
