With the realisation that another major European war was imminent, a 'Special Emergency Edition' of the 1:10560 County quarter sheets was produced in 1938-39, for Air Raid Precaution (ARP) planning.
Most of the revision was of new buildings and roads, and was based on Ordnance Survey revisions and 'ad hoc' surveys. As the title implies, this was a 'rush job', the nature of which can be seen in the way streets are drawn and any added buildings have no infill.
This edition seems to have been produced for all urban areas with a population in excess of about 2000 and is of great value as a record of how far our towns and cities had expanded on the eve of the Second World War. Unfortunately, these maps are very rare.
This example shows the eastern half of the city, covering the important railway works at Cowlairs and St Rollox, the Eclipse steel mills and Parkhead Forge. New houses and streets can be seen north of Cowlairs Park and to the west of Springfield Road.
