Treworgy Planetarium at the Mystic Seaport Museum, in the middle of the green
This armillary dial with a sailing ship weather vane is on the cover photo of Albert Waugh's book "Sundials - Their Theory and Construction" (paperback edition). The dial sits atop a short stone platform outside of the Treworgy Planetarium, on the grounds of the Mystic Seaport Museum in Mystic, CT. To correct solar time to clock time, the dial has an Equation of Time table at the base. The armillary sphere underwent a restoration in the summer of 2015, removing corrosion, repainting the dial structure and equatorial band, and re-stencilling the longitude degree markings.
