After a debate on the age of the pupils in this photo, and when the school photos were done in colour - 1970's - the year of this photo is thought to be c1969.
photo from Alan Dickson with the comment :- 'Barrington CP school 1953 (The queen's coronation year) . This looks like more than one class so could be Class 4 & 5 or 3 & 4.' Alan was in Class 6 in 1955.
