Thought it was time we exploited this new Google Earth feature (apologies if someone has already done so). At the coords go into Streetview. Zoom in and you will find the following:
A blue and white sign on the left (looking South) - number of words (don't include the numbers) = A, number of yards = BCD
A bit further antioclockwise a danger sign with E words.
The cache is at N51 16.(C-B)B(A+D) W 000 15.(E-1)(B-D)(C+E-1)
