Bellow
The leather of the bellow was in poor condition, and the bellow has therefore been completely re-leathered.

Pipework
In addition to repairing damaged pipes by tuning, the restoration of the pipework includes adjusting the voicing to match the 1983 configuration. Where necessary, specific improvements are being made, such as adding side beards to the wooden pipes of the Bourdon 8' and replacing the tips of the pipe feet of the façade pipes. Some of the wooden pipes had previously been fitted with metal side ears that were stapled to the pipe.
The languids of the Montre 8, Bourdon 8, and Prestant 4 stops were irreparably damaged by numerous deep nicks. The Bourdon 8 had also been altered (specifically, the languids had been cut round upwards). The languids of the façade pipes have been replaced. The internal pipework of the Montre and Prestant has been replaced, as has the metal pipework of the Bourdon 8, naturally in the original scaling. The reed pipes had been modified: sleeves had been inserted into the shallots, weights had been added to the tongues, and the resonators had been either lengthened or fitted with holes. All components have been restored to their original configuration.
