We have a vast number of old Ordnance Survey maps available, and are especially strong on flat sheets from before 1940 : the one-inch Old Series, New Series, Revised New Series and Third Edition small sheet series. Other very large sections include the one-inch Fifth Edition and War Revisions, half-inch, quarter-inch pre-1945, 1:25,000 First Series, six-inch, agricultural land use. Plus lots of odds and ends.
All pages have illustrations of the maps being offered, usually with an index diagram showing the sheet lines for the series. The small thumbnail images can be enlarged by clicking once, and once again for a larger image.

We have published six books concerning the Ordnance Survey, and can offer a good list of other books on the subject.
