The Bosbury organ was built in 1871 by Speechly and Ingram of Hereford and improved by Ingram & Co of London in 1897. A small north transept was formed to house it.

There are three manuals and pedals; the action is mechanical. The tone is both full and bright. There are 28 speaking stops: 11 on the great, two on the choir (with three further dummy stops without preparation for additional pipes) and four on the Pedal. The swell is enclosed with a trigger foot pedal to the shutters. There are three composition pedals to the Swell and six to the Great, which also operate the pedal stops. The pedal board is straight and concave CCC to F, 30 notes. The usual manual and pedal couplers are fitted and a somewhat noisy tremulant is activated by a foot pedal.  For organ buffs, a full specification can be found here

This organ replaces a barrel organ made by TC Bates in about 1850, which is now in private hands. It has three ranks of stops: Principal, Stopped Diapason and Open Diapason. There are 19 keys and 51 notes. Originally there were four barrels each pinned to play eleven tunes.
