Ed,
Point 9. The head of the rear (solo) pilot is lined up with the lower wing trailing edge in Gipsy Moths and Stearmans, plus many others. The wing can be put on the sun's azimuth by rolling the wingtip to the sun, then lowering it to the horizon (azimuth.)
The sun does not get high enough to form a complete shadow in the UK winter, but could elsewhere.
Read my posts in Nov 15. Compass reading is not critical for drift correction on the outbound leg. If you apply double the drift error in degrees after 2 hours, you will be back on track after another 2 hours. It is the correction in the right sense that matters. Landfall track is given by sun's azimuth, in this case, - 90 degs. Roll the aircraft to put the sun on the wing, then apply drift. The actual compass reading doesn't matter, but applying the drift the right way does.
