Hi Brad,
I would be very interested to have a copy please. The incorporation of maps into dials is something that has interested me ever since I saw Harvard curator William Andrewes's map dial at Burghley House near Stamford in Britain. He called his a Longitude Dial. It's based on an idea proposed in 1607 by Franz Ritter of Nuremburg who devised a world map projected from Nuremburg, with its lines of longitude arrayed to serve also as hour lines. I think Andrewes makes these to special order so there very few of this sort of dial around! There's more about his dial at http://www.longitudedial.com/index.html. Your dial sounds equally, if not more intriguing.

As you know, the Oughtred dial can be drawn on any azimuthal map projection (Oughtred himself chose the Stereographic). Since the dial is drawn on a map, it's possible to drawn Earth features such as countries as part of the dial. What I've done (and I'm pretty sure this is new) is incorporate the ability to download and use Google Maps in the dial. The technique works with geographic dials as well. I tried to send an example to the SML but the image is 90KB+ so will not pass the size filter. I'd be happy to send the diagram to whomever is interested.
