Well, I have been in Accrington today and I had a chat with my Mum, I think discussing this piccy took her mind of the impending funeral!
She appears to have tied it down to 1968 as she claims I was 6 at the time. A little more info is that the Queen is carrying a small posy which had just been presented by the daughter of the then owner of the Dunkenhalgh. She can't remember her first name but the family name was Burrill or Burrell. This family also owned Mitton Hall in Whalley and were friends of my Grandparents. As suspected, the Queen didn't actually visit Accrington but merely stopped off at the Dunk on her way to the real venue, possibly Burnley (perhaps she needed the loo

)
So I suppose between us, with thought and ideas from everyone contibuting, the mystery is all but solved. Getting a precise date would be brilliant though
