Fred's rediscovered Serle's dialing scale plays an important role in
this video. Fred, did the archeologists contact NASS for advice,
and did the scale come from you? The person demonstrating the scale
could have been a bit more careful to make sure the drawn dial lines
all intersected at the origin of the string-hole, but otherwise, the
scales did the trick!

An exciting find in the Jamestown excavation - a 17th

See the article at:

Be sure to view the video that shows the actual uncovering of the
dial and the reverse engineering that determined the latitude for
which it was made. Note that the dialing scale the archeologist
is using is a NASS scale I provided to members many years ago at
the first NASS conference. (BTW if you haven't yet sent in your
registration for this year's conference in Asheville NC, please do
it soon!) I believe the instructions he was using came from the
Compendium article by Steve Woodbury.
