Wanted to get this down on paper before the ideas floated away. This dial is often referred to as a Noon Mark dial. During those in-between times when people relied strictly on a sundial and then relied on a watch, there was a time that watches just sucked. They were either slow or fast. In addition, time wasn't standardized across the country as travelers moved from cross country by train. To help folks deal with these issues, Noon Mark dials were setup in town squares and provided accurate time of noon. People would stop and correct their watches based on the indication of Noon given as the shadow passed the 'noon mark' on the dial. In addition, homes at that time often had 'marks' on window sills or walls that indicated Noon.
This particular design is about 183 cm tall and 40 cm wide (scale: 1mm = 10 mm). There will be (smaller) dashes to mark the first of each month and an analemma to mark the local civil time. The analemma provides a correction for the yearly 'wobble' of the earth and is is 'tilted' to provide correction for local longitude. The Zodiac is given to provide some reference to the month.
