content with a mere 12 mixture ranks). Abbott & Smith The original foot blowing gear required the services of four men to raise sufficient wind. With the advent of modern technology, it was unsurprising that, in 1894, the Leeds firm of Abbott and Smith replaced it with a Shipley gas engine and compressor. At the same time, a new organ console was provided with a pneumatic stop action. The Schulze key actions and the borrowed Solo manual remained. They also converted the pedal action to pneumatic operation, with the new supply of wind allowing the addition of thumb pistons and other gadgetry. The story is told of the “loss” of the choir mixture arising from the somewhat ill-advised attempt of a verger to search for a gas leak with a naked flame. This action resulted in an explosion causing the loss of the original North Transept window and supposedly the Choir mixture. Curiously there was no apparent sign of damage to the case pipes or any other ranks. A probably more plausible explanation is that Edmund Schulze substituted the 2 rank Flauto Gambe in place of the Mixture originally specified in his father's quotation. Norman & Beard and later works In 1910 the only significant changes were made to the instrument with the replacement of Schulze's “borrowed” solo manual with an independent department in its own swell box. Another new swell-box was provided for the echo organ making it in the words of Magnus Black “inaudible above the traffic except in the early hours of the morning”. The echo swell box shutters have since been removed! A large leathered No1 Diapason, standing in its own separate chest, was added to the Great at this time. It was removed in 1959. The sum total of the Norman & Beard changes was the addition of 8 new stops (i.e. the Solo division and the Swell Celestes). It is believed that the wind pressure to the Great Reeds was increased, but no other changes were made to the voicing. In 1935 J W Walker & Sons provided a new electro-pneumatic action and radiating terraced stop tab console on the south side of the choir (see plate VI). Further work was carried out by Walkers in 1959 including the replacement of the original pedal chests, which after 100 years service were no longer reliable. The Walker console was removed in 1999 when Andrew Carter
