We have a very large stock of the one-inch GSGS 3907 War and Second War Revision maps, which have yet to be put on this site. These maps are on the same sheet lines as the civil Popular Edition one-inch maps, and have an overprint showing the War Office Cassini Grid. It is this grid that is used in official documents of the Second World War.
Please contact us for specific wants.
A full history and carto-bibliography of the series can be found in Military maps : the one-inch series of Great Britain and Ireland.
