The inspiration for this post comes from Dave Brewer from his first edition (1986) “A field guide to the BOUNDARY MARKERS on and around DARTMOOR”. I have added a bit of my own narrative but have also paraphrased Dave Brewers findings contained in the book. I note that Dave Brewer uses “Halsanger” in his book but OS uses “Halshanger”. I have used the latter in this post.
