A mole catcher's gibbet

I remember seeing keeper's gibbets years ago with moles, rats, stoats, magpies etc all hung up on the fence.  I came across this rather gruesome exhibit in Allendale.  It is a mole catcher's gibbet, a rather specialised form of keeper's gibbet.  The mole catcher uses it to prove to his employer that he is doing the work he is contracted for.

I couldn't get the whole length of the gibbet in one photo with the lens I had but I estimated there were over 200 mole carcasses displayed.
