The cache is NOT at the published coords, they are for a 'Waterline Hollow' on the Broadwater Stream, just on the County Boundary.
Have a glance at the 3 collage pictures of 12 related photos in the 'Image Gallery' below, let's call 'em A-L. With the photos, they are arranged as follows;
A B
C D etc
The cache can be found at the following location;
N 51° 21.(A+B)(C+D+E)(E+F) W 000° 56.(G+H)(I+J)(K+L)
You can check your answers for this puzzle at,

I have included an additional waypoint for parking (in a lay by), as the GZ has no suitable parking ( 51° 21.716'N 0° 56.788'W).
Please insure that the cache is returned with some cover. Tweezers maybe required.
As with any of my puzzle caches, if you are stumped or need bailing out at all and you require an extra nudge/ hint or if Mr Googly can't help you then help please feel free to contact me as I'm more than happy to help you.
