Dugdale's England & Wales Delineated, Curiosities of Great Britain
Dugdale's England & Wales Delineated, Curiosities of Great Britain originally used Cole & Roper's 1810 maps, but from 1842/43 it uses maps by J Archer. There is Archer's imprint in the bottom right and a small 14 in the top right (as in 1848).
Scale correct at 15 miles = 53mm, or 7.15 miles/inch, ie 1:450,000.
The railway goes out to Harwich (opened 1854, but shown schematically) and from Barking to Tilbury (opened 1854), but does not have Tilbury to Mucking (also opened 1854).
