Another ***FTF*** to wendykmj !!!
The listed coordinates are not for the cache, but for the wonderfully named Cucumber Woods, which have nothing to do with the puzzle, other than being on the boundary between Oxfordshire and Reading Borough.
This cache was placed on the first anniversary of the day that we found our first ever Leeroy71 Unknown Cache (GC49F9J) - starting what has turned out to be an ongoing journey of puzzlement, discovery, revelation, occasional frustration but ultimately always rewarding endeavour.
Unfortunately, our log is silent on exactly how we solved that particular puzzle, so we will probably not be able to help you with a nudge. But we apparently awarded the cache a Favourite Point, so it is certainly well worth a look.
