I have done several tours of the British Museum with congregation, when we lived in the South. As the Secretary it usually fell upon me to arrange it all. They were good days out.
I am talking up to the mid 1990's . There was a travel firm, called Meander Travel run by a Greek witness, and he organised the tours with guides who were pioneers (A great way to get in your time] The tour of the Babylonian room might have been the one called "The Stones are Crying Out". I have still got the lapel badge they gave us.
Everything was 'spun' from an entirely witness angle . We took our bibles, looked up the scriptures and there before us was the actual evidence. All very impressive.... mind you, the last one that we went on , we were able to see through the 'spin' a little but were much too polite to say so.
More recently when I went down to the Museum, I dressed smart and was mentally ready to tag on to a party if I found one, then ask a few questions. But that day there were no Witness parties to be found
