GSGS 2748 1:20,000 artillery training map Tilshead
56. Nearly two hundred artillery training maps were published during the first world war. With few exceptions they were at a standard scale of 1:20,000, and were district maps photo-reduced from County Series six-inch (1:10,560) maps. Standard sheet coverage was 17,500 by 10,950 yards (effectively 16 by 10 km); most maps were printed in black with contours at 5 metre intervals in brown. They were originally classified GSGS 2742a (the number reserved for the 1:20,000 Western Front maps, the suffix “a” implying the overprinted squaring system), then allocated their own number, GSGS 2748. Most of the known surviving artillery training maps are in the two-volume set in the British Library (Maps 150.d.14). These volumes largely comprise late printings, and earlier ones, such as these three, are very rare indeed.
