🙂 If you get a chance ,have a look at http://www.yorkshireairmuseum.co.uk/
They have a tail gunners section which was manned by veterans.They certainly added a huge amount of information which bought the artefacts to life.
They also have a tail gunners association i think. http://www.yorkshireairmuseum.co.uk/collections/airgunners/index.asp
