Hodiddodd revealed

Congratulations to Val Bird of GHBC who has correctly identified what a Hoddidodd is (picture below)
The prize has yet to be claimed as Val's guess for beever was wide of the mark. I'll make it a bit easier: the Fen equivalent of beever (often pronounced "bavour") is docky.  Google is not your friend here - docky has nothing to do with Linux, dock leaves or a place where ships sail from. Knowing what a hoddidodd is may be a bit of a red herring .....
