When did Erdington Grammar School in Birminghnam open - and when it become Kingsbury School?

Erdington Grammar School for Boys opened in September 1931. It later became part of Kingsbury School, but there wasn't a single date when it changed names. The process involved mergers and reorganisations. The most relevant date is likely 1976, when the Birmingham Education Authority reorganised secondary education and Erdington Grammar School for Boys was incorporated into the newly formed comprehensive school, Kingsbury School. However, the name "Erdington Grammar School" may have been used informally for a period even after the merger.
