Scale 1:25,000

First issued in 1965, these sheets mostly cover an area 20km x 10km. Earlier editions are folded into card covers. Editions published from c. 1980 onwards are paper sheets folded into integral covers.

Final sheets issued in the early 1990s, and were phased out with the arrival of the Explorer series.

Please enquire to see if the sheet you want is available. I have over 1000 sheets in stock, many listed separately, but many not, yet.
