The organ at St. Peter's was built by Gray and Davison for the London Exhibition in 1862 held in the Royal Horticultural Society gardens. The Science Museum now stands on the site. It is said that the organ was then installed in a public house in the East End of London before being acquired by Charles and Bessie Painter of Aldborough Hall, who presented it to St. Peter's in 1898 in memory of their son, Charles Alec, who died on 11 February 1893 aged six months. Herbert Freshwater was appointed organ blower at £1 10s per annum in 1898, for the organ was hand pumped until 1951. The organ was rebuilt and enlarged by Gray and Davison in 1958. Restoration in 1994 cost £17,500 and in 1999 two stops were installed coupling the big pedal to the great and swell manuals.
