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, but no Dugdale imprint across the base.
Scale correct at 15 miles = 53mm, or 7.15 miles/inch, ie 1:450,000.
The railway goes from Barking to Stepney to Fenchurch Street (opened 1858) and from Chapel to Halstead (opened 1860), but does not have Halsted to Castle Hedingham (opened 1861).
