If you correct John Michell's grid bearing of 66.5 degrees to a true north bearing it comes out as 69.23 degrees which is very close indeed to the 69.36 degrees that I calculated.

And in case you, or anyone else is interested in order to calculate azimuth from declination the following formula was used: cos(azimuth) = (sin(declination) (sin(latitude) x sin(altitude)))/ (cos(latitude) x cos(altitude)).
