English Organ

Until the end of 2018 the works in our workshop are influenced by an English organ from 1902. It was built by Forster & Andrew located in Hull and is one of the late works of our workshop. Forster & Andrew built about 60 new organs and were among the most important organ building companies in Northern England at the end of the 19th century. Originally it was bulit for St. Andrews Church in Derby and will have its place on the gallery in the Evangelical Lutheran "Südstadtgemeinde" in Hanover. At first, this instrument had 27 sounding registers, five couplers and one tremulant for the "Schwellwerk". The sound and register system for the manual is based on sliding chests. The pedal registers and their transmissions are controlled by electric magnets or by relay. The wind system was rebuilt after an electric blower has been connected. In this connection, the mechanical scoop system for both double-convolution magazine bellows was also removed. Since the organ has two bellows with separate wind control, the organ can also be played with two different wind pressures, i.e. the swell unit is controlled with a pressure of 115 mm WS, while the wind pressure for Great, Choir, and part of the pedal is played with approx. 100 mm WS.

New location 

Since the organ stands on a gallery at its new location and was to meet the changed acoustic conditions, the following stops were also installed vertically on individual windchests:



  • flute 4' open wood with triangular construction.
  • mixture 3-4 times


  • Tuba 16' full length organ metal bell with separate float bellows and separate electric high pressure blower.


  • Octave bass 8' organ metal open construction.
  • Trombone 16' full length bell made of pine wood.

All added registers are on newly built windchests with electrically controlled disc valves. Since the pitch is beeing changed from the original 451 at 18 C° to 442 at 18 C°, the bodies of the pipes must be extended accordingly. The organ project was started by the organ building company Nikolaus & Förster. Nikolaus & Förster first created the extended sound concept and was responsible for the dismantling. Here, the wind chests and the governor's office were professionally and exemplarily overhauled, the bellows releathered and a new bellows built. A part of the sound mechanics has been restored and a part of the additional shop has been rebuilt in a solid way. Furthermore, the company Nikolaus & Förster has renewed the very badly damaged Posthorn crowns of the Contra Oboe 16' and other cup tips. The organ was initially planned for another church. With the decision for today's installation site, we were also entrusted with the continuation and completion of the work. We would like to take this opportunity to thank them for the collegial and friendly handover of the project. The main tasks in the Halberstadt workshop were the new construction of the additional pedal shop, the new concept and implementation of the electronic control of the additional shop. The restoration and intonation of the pipework and the heavily damaged reedwork. The pre-assembly in the workshop with the reorganization of the organ system. Housing restoration and completion, reconditioning of the swellings and the construction of side walls, landing and the many small tasks such as the integration of the new stops into the collective steps...
