The organ was originally built in the 1950s for Royston Methodist Church, Cambridgeshire and is the 'Miniatura A' model consisting of 2 fully enclosed ranks of pipes - Diapason and Rohr Gedackt. 

In the late 1970s, the organ was moved here to St Mary's where it replaced a single manual Walker instrument. The detached stopkey console is located at the front of the church behind the left hand choir stalls with the pipework situated at the rear.
