I almost would bet the key figure is 48" and this is split into the 3 segments. Does this fit into the daisy wheel layout system? 12 is an important number now and much more so in the past, 12 signs of the zodiac, 12 apostles, and the measuring system in base 12. When did the metric system come into wide use in Europe? We do have 10 fingers but that is too easy.

Gabel, can you shed some light on the daisy wheel and its relation, if any?

This could be a new topic.
