Sudbury Ephemera Archive is hoping people will come and help identify Sudbury Grammar School cadets from 1934.
The photo is of the school’s cadet corps just five years before the start of the Second World War and it is likely that many of the pupils pictured fought in the conflict.
The Archive collects, stores and displays letters, brochures, and many other paper records of the town’s history.
Its chair, Sue Tibbetts, has a double interest in the photo, having taught at All Saints Middle School which replaced the grammar school. She remembers the box of corps items being under the school stage, often used for props, but said she is not sure of its whereabouts now.
Anyone wishing to see the photo should contact Mrs Tibbetts on 07846 885909
