This is an “a propos to nothing” post, as the old Danny Baker Radio London show used to say.
Here is a mystery map of the estate in North Kensington which was redeveloped after 1950 – the area has been extensively bombed by the Luftwaffe. It seems to be based on the 1897 Ordnance Survey map but has been redrawn.
It depicts the original layouts of Treverton Street and Hewer Street along with the long-lost Raymede and Rackham Streets.
