What happened at Hendon Central in 1941?
The answer apparently is NOTHING, at least nothing of such topographical significance as to account for the curious discrepancies in detail there are thereabouts between Six-inch sheet Middlesex VII SW (revised 1935-6) and 1:12,500 GSGS 4157 sheet 56/20 SW (A), (revised 1941)…. I ask the question ‘Who dreamed up the imaginative but largely false reconstruction of Hendon Central Circus portrayed on GSGS 4157 and why?’
