Other points to remember with maps is that some revisions were not complete. The ones labelled c1913-15 in a few places seem to be out of date , in that the attribution of some features seems to refer to a slightly earlier time. this is also true of the c1889 large scale maps, where some companies listed at a particular place appear there in directories only up to sometimes 6 years before that date . The c1938 revision is in many cases incomplete, with areas blank, probably because of loss of material during bombing of the OS buildings in Southampton in the war
