The grid ref given here is that matching the spot where in 1913, an oak coffin was discovered during ploughing. It's 1.67m in length and contained a few teeth, remains of stitched calf skin, a drinking cup and flint scraper. Radiocarbon dates of 2400-2200BC were determined, suggesting an early BA date for the burial.
the C&R stone does not seem to have been part of this burial, but it's exact findspot is unclear.
One of the lucky cup-and-rings inasmuch as it was about to be broken up & used for walling when, upon turning it over, the carving was discovered. Although it has been described in the more recent works of Stan Beckensall, it apparently now resides in the Newcastle Museum of Antiquities.
