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 later 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 - making this the late 1840's edition.
The boundaries of the Hundreds are coloured, but in a pretty loose, not to say careless, manner.
Scale correct at 15 miles = 53mm, or 7.15 miles/inch, ie 1:450,000.
The railways shown are a bit of a puzzle: it has the Marks Tey to Sudbury (authorised 1846; opened 1849), the Ilford to Ray House to Epping line (auth'd 1846 but never built) and the Thameshaven line (auth'd 1836 but never built - cancelled 1856), and also a very odd North Ockendon to Tilbury Fort line (never built, or authorised); however it does not have the Stratford to North Woolwich line (auth'd 1845, opened 1847), or the Braintree to Witham to Maldon line (auth'd 1846, opened 1848) or the Manningtree to Harwich (auth'd 1847, opened 1854). From all these contradictions I estimate a date of 1846. See also Archer's "1847" map.
