The Northern Antiquarian (TNA) also have a page for this well preserved cairn and cist, see their entry for Drizzlecombe 13, Ditsworthy Warren, Sheepstor, Devon, which includes a drawing of the cairn (after Butler 1994) and some folklore.
What made me smile was TNA's paragraph, accompanied by a photograph, which said "One of the most important finds in recent years—as the photo above shows quite clearly—was the fact that before joining The Goons, the British comedian Spike Milligan used to live in this prehistoric tomb. When asked why he didn’t live in a house like other normal people, he invited us in for a cup of tea. Some historians believe that the person in the photo is in fact Mr R.H. Worth—author of Worth’s Dartmoor—but Mr Milligan insisted that Worth was an imposter!"
Something is not right. This message is just to keep things from messing up down the road
