Not suggesting they weren't, just suggesting they weren't as common as the
simpler Mannheim types.

Heck, in the movie "Apollo 13" one of the engineers is shown with a slide
rule that looks suspiciously like an old Sun-Hemmi/Post 1447 Mannheim.

BTW I've found the best resource for figuring our which old Sun-Hemmi you
have is the online /catalogue raisonne/ that Paul Ross has at his webiste:
