In the inter-war years, Compton built many of their 2 manual 4 rank instruments for city suburban churches and one such example can be found at St Mary and St John Catholic Church in the Erdington area of Birmingham.

Job number A354 was built in 1937 and originally installed at the front of the church to the right of the communion area In the 1980s the church was refurbished and the organ was moved to its present location on the rear gallery which is enhanced by the excellent acoustics of the church.
