Another cache in what has the potential to become 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 will 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
