Postcode Cache 147: Papa Lima 21 Letterbox Hybrid

UK postcodes, introduced by the Royal Mail (then called the General Post Office) now serve several purposes. They were originally intended to help sorting offices categorise the postal mail, however they are also used for calculating insurance premiums, aggregating census statistics, and for designating coordinates for route planning devices. Postcodes were first used in London in 1857, and expanded to several large cities in 1939 , reaching the rest of the UK between1959 and1974.

As postcodes are used on posted letters, we thought we'd make it a letterbox cache . There is a rubber stamp and ink pad inside for you to use with your own notebook. Please be sure to leave the stamp and ink pad in the cache afterwards. If you have your own stamp you can also stamp the logbook; if not, just sign as usual.

The cache is not at the posted co-ordinates, but can be located by solving the puzzle below.

• A is the length of the name of the river that flows through Ivybridge
• B is the length of the name of the river that flows through Lutton (in PL21)
• There are two Inn's in Ugborough, both with nautical names, C is the Length of the longest nautical name
• There is an Inn in Modbury named after another city in Devon, D is the number of first letter of the City.(A=1,B=2,C=3....)
