The cache is not at the posted co-ordinates. There is a hint within the checker. On hiding, by minadequate, the cache contained: log, general geoclutter and a unregistered TB for the FTF. Thanks to the Melksham Steak Meet event's secret Santa for most of the cache and contents.
The cache is most safely approached from the west.
I have minadequate's hint sheet if you are really stuck with anything.
