Maps

We have a large collection of Ordnance Survey maps, e.g. 1907 series 1:2500 sheets covering most of mid-Cornwall and North Cornwall and some sheets from West Cornwall and Devon; 1973 series 1:2500 covering most of mid-Cornwall and some of West Cornwall and Devon, and 1906 series 1:10560 covering most of mid- Cornwall and some of Devon.

We also have aerial photographs of the china clay area dating from 1948.
