One-inch (1:63,360) map of England and Wales, sheet 161, temporary advance edition with hills
|
21. Hill engraving took so long to accomplish that the Ordnance Survey determined upon the temporary measure of issuing an advance edition of England and Wales sheets with hills printed from transfers to zinc. The programme began with this sheet 161 in 1892. That it seems not to have reached legal deposit collections, nor gone on sale to the public may have been caused by its erroneous appearance in the publication report as sheet 162; thus two copies in private collections are the only ones so far recorded. The advance edition of sheet 161 was published in a second form late in 1894.
