I love maps as well.
Between tiling the bathroom and a zillion other things (jobs) while Mrs is away I have scanned a 25" to the mile map of Wallasey Village area (2 sections on A3 scanner), a 52" to the mile map of B'head Woodside area (again 2 sections) and a street map of Wallasey & B'head (4 secions at A3). All dated around 1960 so "old" but within memory of more mature members (cough, cough).
Each of the 8 files is 17 Meg!
I can send then to Mark by arrangement and maybe Mark will use Photoshop or whatever to recreate the individual files into one. I tried that with Paintshop pro and it was a mess.
That is not essential because I suggest that the maps are simply held "on file" for access by Mark and a few others and then when a topic arises needing a map a sub-section showing the area concerned can be cut amd pasted into the thread.
Tomorrow i will order a set of the Godfrey maps for Wallasey area + Bidston Hill
around 1900. I have been meaning to do that for a while but your post reminded me. I also need the map for north Anglesey but that is for family History
