An uncle on mine, born Beatty Road, Bedlington, 1938 said the story about the Monkey in the window was not true.
However tThe Barrington Arms got a paragraph in Issue No 138 - February/March 2014 of The Northumbrian - Gordon Wilkinson (journalist I think) on a subject 'How a Pub makes a name for itself' has written :-
...... However a look in the window of the Barrington Arms in Bedlington during the Second World War could have brought good news to those fancying a pint. Beer was rationed in those days but it could be in short supply , so the landlord would stick a stuffed monkey in the window to tip off those in the know that he had received a consignment. The pub has been named the nicknamed The Monkey ever since.'

No mention of where he got the story from.
