The organ is based on the early instruments of Eberhard Friedrich Walcker. Its inspiration here was primarily the largely original model in Hoffenheim (1848, Opus 62).
The model for the dominant Physhamonica with its own keyboard was the instrument in Schramberg (1844, Opus 46).
A strict reconstruction was not intended. Thus we find, among other things, the second manual located in a Swell Organ.
The technology for playing and registration, the use of cross-coupling and the extended range to c'''' or g' goes well beyond historical models.
Due to the extremely cramped space and height proportions on the West Gallery, the organ received a new mechanical slider chest instead of the the cone chests used in the originals. In the construction of the individual registers numerous characteristics were adopted from Walcker.
