This might be of interest to some people, as part of my family tree research(my father attended Berridge in the 1920's-30's) I have just picked up a copy of the school history.
It's a fascinating booklet which covers from when the school was first built upto the 1970's, it contains maps and old school pictures. You can get it from the school for a donation to school funds (£5) to cover photocopying, if you are interested you need to phone the school to give them time to photocopy it and arranged collection.
cheers
