Just added a little bit of info about the Fort Grey Shipwreck Museum, Rocquaine Bay, Guernsey (http://www.detecting.org.uk/html/Fort_Grey_Shipwreck_Museum_Guernsey.html), it is a small museum but well worth the trip if you are visiting the channel islands. The staff were very friendly and knowledgeable. A must visit for divers and wreck enthusiasts.
