I went to the NMR in Swindon recently having pre-ordered aerial photos of the areas surrounding Bodmin, Wadebridge, Lostwithiel. I also looked for the Red Line in Wiltshire. The Wiltshire photos show the ditches, pillboxes roadblock clearly and those on the Bodmin Stop Line show almost nothing!! I took photos and photocopies of some but this is proving very frustrating! I have found some records of the Home Guard in Lostwithiel however which explain the defended locations there....but nothing on Bodmin or Lostwithiel.
