We suspect that a lot of younger cachers will never have seen one of these signs. If you do recognise the sign then you are showing your age!
Please be aware that stealth is required here as it's very close to an adjoining property and despite a couple of visits we have been unable to speak to the occupants. It is also a very dark country location so torchlights at night would be a giveaway, please consider this.
We would love to know if you have knowledge of any other signs from this older era.
