When you have found the code, you will need to use it to fined the location of the cache
The three digit code is ABC
The cache is located at N 52° 51.(495-ABC) W 003° 33.(085+ABC)
The same three digit code is the combination to the lock on the cache.
As the lock has now rusted shut. I have now adapted the cache container, so you can now access the log book without having to undo the lock.
In recognition of completing the clock series I will be pleased to send a copy of the above badge for your profile page
