Just had a reply sent to me about a hut near the gorge in Glencoe known as the Squirrel's Drey. I knew it was used by climbers but I was told that it appears to have been used / built by people (Home Guard?) manning the nearby gun positions.
The message sent included this which I thought might be of interest here.
Glasgow climbers still have a hut in the Coe, Jacksonville, up towards The Kingshouse. I believe it was based on a shelter abandoned by the Commandos training there during the war.
