In addition to what remains of his work in the organ at Roskilde Cathedral and the "empty" cases in the transept of de Aa Kerk in Groningen I find a wonderful instrument in Denmark.
After the death of her husband, King Christian III of Denmark in 1559, Queen Dorothea moved her Court to the castle at Sonderborg (position 54 55N 9 49E).
It appears that the Raphaelis organ located there has been reconstructed to allign more with his workmanship in favor of a later rework in around 1696. It is a very unusual organ in several ways. One striking thing is the stop action for the upperwork. They seem to consist of direct linkages to the sliders that are acuated by means of long extended handles that hang from the "impost" of the case sides. One would have to stand and lean way out to swing these levers or have an assistant to make registration changes in that division. The lower positif has the usual draw knobs.
The next thing that might be mentioned is the pitch of the organ at a fourth higher than standard:
temperament: meantone.
Stemmetonehøjde: a' = 624 hz. v/ 18° C. !!

I hope other member will add insights on this builder and other information they might find as well as additional examples of his work.
