Dear All,

In anticipation of this thread, I took up the
matter of the location of the sundial with its
designer/maker, Quinten Hollick.  He lives not
far from the site.

As you can see from his reply below, we had
this discussion over 13 years ago!  The tree
wasn't so big then!

It sounds as though he was attempting to set
the stone at the U.K. Ordinance Survey version
of the Greenwich Meridian.  This runs through
the Bradley Transit Instrument at Greenwich
which is 5.79m to the west of the Airy Transit
Instrument which was used to define longitude
zero in 1884.  The GPS meridian is to the east
of the Airy Instrument.  See:

Using the GPS kit of the 2001, you could
choose different reference systems.  I
didn't get to the bottom of how he set
the stone up in the first place but he
went out and did some checks.  You can
see from his report that there are still
some outstanding questions.  I didn't
press him further.
