Dugdale's England & Wales Delineated, Curiosities of Great Britain
Dugdale's England & Wales Delineated, Curiosities of Great Britain used Cole & Roper 1810 maps in its 1835 edition, but in 1842/43 and here it also 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 - making this the 1848 edition.
Scale correct at 15 miles = 53mm, or 7.15 miles/inch, ie 1:450,000.
The railway goes from Witham to Maldon and Braintree (both opened 1848) and from Marks Tey to Sudbury (opened 1849), but does not have Manningtree to Harwich (opened 1854).
