Great series of maps Richard, especially the 1:50,000 R.E. map, it is zoom-able and you don't lose any of the detail, plus it shows the kinks in the line that 90% of other publications (like the Osprey map) don't. I'll definitely be spending some time today examining them, thanks very much for posting. Dave
