A fascinating can of worms (or is that worm drive?)! My Quintant's scale appears to not have been double reading - rather it was single-reading with a vernier, and the labeled arc was 180, but practically speaking could not read much past 140 deg. See pic below.
Btw, I assume the curious have already noted that there is a nice dicsussion of terrestrial use ssextants tarting on page 140 of Bennett's "Taking The Stars"
