Info from “Southern England – An Archaeological Guide” – James Dyer (1973, Faber):
Opened in 1869 the central mound of the Three Barrows contained a cremation burial, with a small grooved bronze dagger, bronze pin, a pygmy cup and a necklace with beads of lignite and fossil encrinite.
Other barrows nearby produced inverted urns containing cremations. Finds were in Rougemont House Museum, Exeter, but this has closed and it is not clear where the objects are now, unless anyone can help?
