Ok finaly got around to contacting my central county archives. they
have large numbers of 6 inch to the mile and 25 inbch to the mile maps
and a few 1 inch to the mile maps. They will provide electronic
versions for a fee however they are playing silly buggers with
copyright (although I may be able to get around that) . I will know
more once I've sent some stuff in writeing to them.
