Here's an odd one. Anyone know where I can find records of magnetic variation at historic points in the past?
Specifically the need is to reinterpret maps drawn on the Western Front in the first world war, which were orientated in relation to magnetic North. But where was that in 1916-18 if you were in France?
Much appreciate the answer if anyone knows.
