This unusual equatorial sundial was designed by BSS member Robert Scott Simon in 1988.  The time scale is mounted at the end of a long sloping support, and rotational adjustment is provided to twist the dial by means of an adjustment screw, according to the Equation of Time correction needed for 25 different date settings. Time marks on the Equator band show the hours using Arabic numerals from 8am to 9pm, with half hour divisions. An explanatory plaque is fitted to the concrete pedestal.
