This is a number in a series of caches where a red telephone box is in close proximity to a post box.
The only rules are that they have to be able to be photographed together, be not more than 100’ apart and the phone boxes have to be red.

When finding this cache do be careful of the roads as it is a very busy farming village!
First you will need to complete a Jigsaw Puzzle and collect some info on completion.
To start the Jigsaw Puzzle you will need to use the link below.

After collecting this info you will then need to visit the Fine Pair which is at the Posted Coords where you can collect the rest of the info that you need.
On the Post Box you will need to find the Postbox number.
# The first number =D
# The third number =E
# If you give the first letter in the Postbox number it's numerical value in the alphabet and minus 3 from your answer this will =F
The cache can be found at: N 50 (E-F)(B-D).(B-F)(C)(E-A) W 003 (C-B)(B/2).(B+F)(C+D)(C-B)-D)
Checksum for all digits of the Final Coordinates =55
Hope you find the cache!
HAPPY CACHING!
