This is the top-left corner
taken from Ordnance Survey 'Popular One-Inch Series' of maps,
sheet 74: Edinburgh.
This map was published in 1925:
"Revision Full 1923 with later corrections".
When this map was published,
Edinburgh extended as far west as Cramond Island (upper
centre-left). Now, in 2006, the boundary extends as far west
as Queensferry (top left corner).
