Found a burnt box

Walking the dogs this morning I found a small gully at approc 544 684 that has had all the gorse burnt away, there was a half melted grey pill pot with a stamp inside, the stamp appears to have a small trowel and fork on it. Does anybody know whos it is so that I could let them know. I did pick it up and bring it home.

I believe that is one of a walk called mo's garden put out by the cockernuts.

Anybody have an email address for them?

Alan have pm`ed you the address

Thank you
I chipped away the melted plastic and dug out the stamp amazingly despite the melted and burnt plastic the stamp is actually fine, the backing is wood and is not even charred. If I can get it back to them they can put it out again.
Thanks
