Similar query - and I have no date - a stick of I believe small bombs fell in St Lawrence Drive and Rodney Gardens in Eastcote (between Pinner and Ruislip). Only reason I know is that we had a bit of coving in the living room that continually fell down and Dad explained it had benn like that "ever since the bomb on the corner" (of the road, not the house). Anyone know wher I can find the details.
