I READ with great interest the article by Dr Ann Pulsford about the collection and use of sphagnum moss from Dartmoor during and immediately after World War One. I am currently involved with research into the collection of the moss and would be extremely interested to hear from anyone who has knowledge, or better still a picture, of the badge mentioned in her article.   All my inquiries regarding the badge have so far 'come to nought' and I would really appreciate any help.
