The J.W Walker organ which we placed in the Engelmunduskerk at
Driehuis has been registered as opus 781 in the order book which
still exists. The instrument was made in 1865 for the Holy Trinity
Church, New Wimbledon, London. The Great Organ had 8 stops
amongst others a spare slide (Mixture 3 rks.) and the Swell Organ
consisted of 6 stops all starting from tenor-C. For the gamut-C
octave the pipes of the Stopped Diapason of the Great Organ were
used by means of a transmission.
The Pedal Organ had a Bourdon 16 ft. (transmission from the Double Diapason of the Great Organ). To quote the order book, the instrument was manufactured “of the best materials & workmanship”. Probably during 1877, the organ was transferred to the St. Saviors Church in Batterseapark, London, where remained until December 1992. In 1903 the Swell was extended to full compass. The soundboard was renewed and the Swell Box was drastically enlarged. A Double Diapason 16 ft., a Gamba 8 ft. and a Voix Celestes were added. Moreover, voicing adjustments were made following the prevailing fashion, and a Tremulant was added.
In 1993 the organ was restored and provided with a new case which was designed by F.R. Feenstra himself. By means of revoicing, the pipework from 1903 was restored to the sound-picture of 1865. The Voix Celestes was replaced by a Mixture 2 rks. As yet, a Sesquialtra was placed on the spare slide. The Great was extended with a Trumpet 8 ft.; the Pedal was extended with an independant Grand Bourdon 16 ft. For these extensions, pipework by W.G. Vowles from Bristol (1873) was utilized.
