GSGS 4136 Ireland one-inch (1:63,360) sheet 336, first edition
17. The intention to publish the military one-inch map of Ireland in the standard 205 sheets was cancelled in June 1940 and the large sheet GSGS 4136 in 76 sheets was published instead. The first edition was superseded by the second within weeks, and before the end of 1940 the third edition was already in progress. Thus sheets of the second edition are uncommon, and those of the first edition almost non-existent: six single copies have been recorded so far. This and 18 are two of those six.
