The original 5 bells in the tower were augmented to 6 in 1928, with the addition of a new treble, all hung in a new oak frame. The oak frame, solidly and accurately constructed, is still in use in the tower today as the main sections of the 8 bell frame. The following year, 1929, the new organ loft, made from the old bell frame, was dedicated at a service by the Archdeacon of Ely.
The service sheet announced:
This loft and the treble bell were given, the bells were rehung and the organ improved, in gratitude to God for the men who gave their lives in the Great War and for other benefactors of the Church and Parish 1929.The event was reported in the local press:
Dedication of Organ Loft.- The dedication of the organ loft at the parish church by the Archdeacon of Ely (Bishop Price) took place on the 16th inst., in the presence of a large congregation, which filled the church. Before the service the bells were rung for half an hour, and the Archdeacon, in the course of his address, said that Trumpington was the only place in his Archdeaconry where he had been welcomed with bell-ringing when he came for his visitation. Turning to the organ loft and referring to the list of benefactors, the Archdeacon said that the list combined in the happiest way men and women of various gifts and stations of life. He added that the list was not complete, and that out of deference to the wishes of the late Mrs Foster, the Church Council had felt obliged to their own great regret to omit the names of Ebenezer Bird Foster and of Mrs Foster herself from the honoured place which their kindness and generosity had earned for them in such a list of benefactors. The collection, which is to go to help to provide a church at Dunblane in Canada, amounted to £20 12s 1d. The new treble bell, inscribed "Good people, come and pray. The gift of Arthur Edward Chaplin to Trumpington Church; 1928." and cast by Messrs Mears and Stainbank, was dedicated on 30th September, 1928. The bells were hung in a new oak frame by Mr R. White in 1928. The organ loft, the cost of which has been largely paid by the late Mrs Pemberton and by Mr and Mrs William Pemberton, was designed by Mr Ernest E. Bowden and built by Messrs L. and C. Mobley, using as far as possible material from the old bell frame. The organ has been thoroughly restored, re-voiced, and improved by Messrs Harrison and Harrison, of Durham. These three pieces of work have been done as one memorial at the cost of about £950, and of this sum almost all has been given by parishioners of Trumpington.
