You are welcome Sir, I cut and pasted the technical data from a website. According to the site the BBC mentioned her on a program recently, but the details were no longer available. You can get pictures of her if a relative served on her and you are interested here is the data site url:http://www.battleships-cruisers.co.uk/bellona_class.htm
Just scroll down and she is the first photograph you come to.

Yours, Aye. Dave
