Another cache in a National Numbered Series of Letterbox Hybrid caches, placed to mark one of a diminishing number of post boxes placed in Queen Victoria's reign and still in use for regular collections by Royal Mail.
A few simple guidelines apply to the series (subject to amendment):
- The post box must carry the Royal Cipher of Queen Victoria (in whatever format)
- The box must have regular collections by Royal Mail
- The box must be in the British Isles (so United Kingdom and adjoining Crown Dependencies).
- Any style or colour of box are valid as long as the above all apply

A short off-set cache based on the traditional Victorian wall box located in Kersbrook near Budleigh Salterton.
The coordinates given will take you to the Post Box itself. The cache is not there, but is hidden only a short walk away. There is plenty of roadside parking very near to the post box and this is the nearest parking for the cache itself.
Visit the post box and answer the following:
Number on the lamp-post opposite = A
3rd digit of Post Box number = B
Monday - Friday = C.DE
The cache can be found at : N50 38.ABA W003 19.DCE
Please watch out for people approaching from both directions!
If you know of an eligible post box and would like to add to this series, please apply to Team Hippo for a series number, giving the following:
- Location as in place name (and street if applicable)
- Location in Lat Long format (DD MM.MMM)
- Postbox number
Please note that featured post boxes should comply with the guidelines above. Caches should be Letterbox Hybrid type (and therefore contain a LB stamp), whether placed at the published co-ords, or a simple offset multi, or multi-stage multi, or more of a puzzle style format.
