Here's a shaded map for 1935 - the outline comes from an Alternate History forum but is obviously based on the Boothroyd drawing. I've removed most of the urban insets but have kept London, which has so many tiny seats that it can't be illustrated very well on the larger map.
I love these strength of seat electoral maps. Brilliant
The striking thing about this 1935 map is how similar the pattern is to most post 1945 maps. This looks very similar to the 1979 map when Maggie Thatcher luckily defeated Jim Callaghan mainly due to the Winter Of Discontent and winning the subsequent vote of no confidence by 311 votes to 310.
That's despite Labour winning only 154 seats in 1935 compared to 269 in 1979.
